10 Loudspeakers Trends That Should End

10 Loudspeakers Trends That Should End

As a loudspeaker reviewer, I get exposed to a lot of different speakers over the course of a year, so I see a wide variety of practices performed by speaker companies. Much of these practices are very logical as would be expected of manufacturers with years of experience. However, some of the things that these companies do are long overdue for an expiration. These include marketing practices, design decisions, and logistical activities that defy common sense or verge on the absurd. Here is a list of ten of these trends in the loudspeaker business that I hope to see come to an end soon.

1.) Dual Binding Posts on Normal Speakers

One engineering practice that is very often nonsensical is the use of dual binding posts on normal home audio loudspeakers such as bookshelf speakers and non-large tower speakers. By non-large tower speakers, I mean a floor-standing speaker that doesn’t have a heavy-duty bass driver section that could actually benefit from a serious amplifier beyond the standard one or two-hundred watts or so that many of us have in our mass production AVRs. Are you wondering if you have such a speaker? There is a good test that will let you know for sure: if you have to ask, you don’t have one. Few people own home audio loudspeakers with that level of capability like these monsters from Status Acoustics.

dual binding posts 

That isn’t to say that your speaker won’t benefit from more wattage than what your name brand AVR can supply, because many normal floor-standing home audio speakers could probably take more power than what a typical AVR can give. Rather, bi-amping (and especially bi-wiring) isn’t the best way to go about that. For starters, many users would be tempted to use different amps to power the different sections of the speaker since they might have a spare 2-channel amp laying around with their AVR. The problem with that is that now there is a good chance that the bass section of the speaker is no longer level matched with the tweeter/midrange section. The only way to be sure that it would be is to use the same amplifier on the same gain settings for both sections of the speaker. What is more, many people would be tempted to use their AVR to power one of the sections of the speaker, and that potentially compounds the problem because there might be a processing delay on the pre-amplifier outputs that can cause an extra latency on the bass section of the speaker.

Some AVRs have settings that will enable them to be used to bi-amp the main speakers, but the problem with that is it usually doesn’t grant you any more headroom since the power supply is shared by the amplifier circuits for both sections of the loudspeaker. The best approach is to just avoid bi-amping the speakers and use an amplifier with enough power for the dynamic range that you want.

Dr.ASo why do loudspeaker manufacturers put dual-binding posts in speakers that do not realistically benefit from it? The answer is that it makes the speaker seem fancier and it’s cheap to do. My wish is that they would drop this pretense and just use a single set of quality binding posts for any home audio speakers except for the truly massive ones. Dual binding posts are more often a means of screwing up the set up of a speaker system rather than an opportunity for an improvement in the sound.

Editorial Note by Steve Feinstein:

The best way to bi-amp is to use two identical amps and use the L for HF and the R of the same amp for LF. This guarantees perfect matching of amp gain, noise/THD characteristic, etc. Per definition of bi-amping, as long as you’re still going through the speaker’s internal passive x-o, you’re not really bi-amping.” This whole thing is so bogus. Only external amps w/external active x-o’s count as ‘bi-amping.’

As I’ve written before in my ‘Insider’s View of Product Development’ article, there are lots of “customers”: The end-user, the store buyer, the store or online salesperson, reviewers, etc. Some of their needs overlap, some do not. “Bi-amp” terminals are mostly aimed at reviewers.

But…..always remember the 5x or 6x Cost-of-Goods-to-Retail price factor (also explained in detail in that article). If bi-amp terminals and the larger terminal cup cost the manufacturer an extra $5, then the retail will have to go up by $25-30 per speaker.

2.) Small Feet on Big Subwoofers

I review subwoofers as well as regular loudspeakers, and I have had to deal with a slew of humongous subs that had feet that were too small for the size and weight of the unit. Regular readers will know the manufacturers that I am talking about because I do mention this problem in those reviews, but I am going to name the worst offenders here anyway: SVS and Monoprice Monolith! The shame of this is that these manufacturers make outstanding products otherwise as we have seen, in review after review.

big sub small feet

The main problem is the feet that they use on their large and heavy subs do not offer as much clearance for fingers as they should for lifting and lowering the subs on and off the floor. Both manufacturers in this instance use some small plastic conical feet that only give about a ¾” clearance from the floor. While that might seem like just barely enough height for fingers to get under, the problem is that these subs sink into a carpeted flooring and can compress the carpet fiber so that there is very little space between the sub’s cabinet and compressed carpeting. That creates a potential pinch point for those who are setting the subs down on carpeted surfaces.

Among SVS’s subs, this becomes a real problem in the 4000 series (except for the PC-4000) and 16-Ultra series subwoofers, since the weight of all of those exceeds 100 lbs. Indeed, the weight of the PB-4000 is 153 lbs. and the weight of the PB-16-Ultra is 174 lbs. It is not so bad with the 1000 Pro series and 2000 Pro series since they are relatively lightweight. Monoprice’s Monolith series, on the other hand, are all very massive subs; the 16” THX Ultra is 171 lbs. And the M-215 THX Ultra is a staggering 216 lbs. I could easily see any of these subs crushing someone’s fingers sitting on a dense carpeted surface in a lowering-it-into-place accident.

Dr.AWhy do these manufacturers use such small, wimpy feet on such giant subwoofers? The answer is that the subs look nicer when the feet are not exposed. These feet are not really visible, especially on carpeted flooring. What is more is that these have to be some of the cheapest feet to buy in bulk quantities out there, so it is a win-win for these manufacturers. However, in my opinion, these feet are a hazard for consumers. My recommendation is that these manufacturers use feet that offer at least a 1” clearance, but 1 ¼” would be better. That should give people adequate clearance to safely lift and lower these subs on carpeted surfaces.

Editorial Safety Note: Use safe lifting techniques with large speakers or subs!

It only takes one bad lift to cause serious damage to your spine that can lead to years or even a lifetime of back pain! Always follow safe lifting practices for handling speakers and subwoofers. Here is a good guide for safely lifting these types of items, and here is a list of sensible tips. Always have someone help you lift a large subwoofer. If you have to carry a large sub up or down a staircase, always use a dolly, even if you have other people around to assist you. I always use a shoulder dolly strap system with a buddy when I have to move a large subwoofer anywhere. You are only given one back, so don’t play Russian roulette with it in order to save some time or convenience on moving something heavy.

3.) Matte/”Satin” Finish Confusion

Something that should stop (but is unlikely to) is when manufacturers claim a “satin” finish on products that really couldn’t even claim a matte finish. If you are purchasing a loudspeaker or subwoofer that claims a satin finish, beware. In my experience, it is more likely to be a textured vinyl finish unless you are paying for a premium item. These finishes have well-defined meanings that have been blurred by marketing departments trying to make the product appear nicer in brochures than they are in actuality. Proper “satin” finishes are silky and very smooth and do have a reflective sheen although a lot more diffuse than a gloss finish. A true satin finish is smooth to the touch and has no texturing. A proper “matte” finish should still be smooth but has very little light reflectivity or sheen. Matte absorbs light. It would not properly have a rough texture though.

textured vinyl2 

Textured vinyl finish- this is not satin!

In many instances, I have seen speakers that have a satin or matte finish listed in the specs but in reality, the speaker has a textured vinyl finish. That stretches the definition past the breaking point. These speakers should just list “textured vinyl” in the specs as the finish. It is not as glamorous, but it isn’t really all that bad either. The nice thing about these textured vinyl speakers is that they are a much more durable finish than a smooth satin or matte finish, and fingerprints don’t easily show up on them. It would be a bummer for someone who is looking for an upscale appearance for the product to order something promising a satin finish and end up with textured vinyl, and it is due entirely to deceptive marketing. I would guess many people are savvy enough to not expect a true satin finish on a set of speakers that cost $200 even if it is listed in the specs, but a lie is a lie, and it should come to an end.

satin sheen 

A real satin black finish

Dr.AIf you are a speaker company and want to oversell your loudspeakers, just use the vague technobabble that means nothing in terms of loudspeaker design but which we sometimes see in marketing anyway, such as: “high-definition,” “HD-ready,” “audiophile-grade,” “reference-grade,” “time-coherent,” “low noise,” “three-dimensional,” etc. At least that kind of language can’t mislead since it contains no meaning to begin with. No need to mislabel a specific kind of finish type.

4.) Not All Non-dome Tweeters are “Ribbon” Tweeters

If we were to trust loudspeaker marketing departments, it would seem that we are living in an era of a ‘ribbon’ tweeter renaissance. Where once there were only dome tweeters for home audio speakers (with a few exceptions), now we are flooded with an assortment of affordable speakers using “ribbon” tweeters that claim a higher fidelity. Except they aren’t. True ribbon tweeters are still relatively scarce and remain primarily on fairly pricey speakers. They certainly can’t be found on any models priced less than $1k/pair. So what then are all of these so-called “ribbon” tweeters on lower-cost loudspeakers?

Ribbon diagram 

Many tweeters being sold as “ribbon” tweeters are really either AMT tweeters or planar tweeters, and all of these tweeter types have very different methods of transduction. First, we have to define what a proper ribbon tweeter is, which isn’t difficult, since mechanically speaking, it is one of the simplest tweeter designs. Ribbon tweeters work by suspending a very thin strip of aluminum between some powerful magnets. Alternating current is sent through the aluminum strip, and the accompanying magnetic charge of the electrically-charged strip whips it back and forth in the permanent magnet’s field. The aluminum strip is so light that it can easily oscillate to very high frequencies well above that of human hearing.

planar tweeter diagram 

Planar tweeters work by printing a conductive film trace on a flat plastic diaphragm that is usually rectangular in shape and then inserting that diaphragm between grids of magnets. The conductive film trace is electrically charged with alternating current, and the corresponding magnetic charge of the electric charge is enough for the conductive film to move the entire diaphragm back and forth very rapidly. A key difference between planar tweeters and ribbon tweeters is that the charged element of the moving assembly in the planar tweeter composes only a small fraction of the moving assembly, whereas in a ribbon tweeter, the charged part of the moving assembly is the entire moving assembly. Since the entirety of the moving assembly of a ribbon tweeter is conductive, it doesn’t have much electrical resistance, so in order for it to work with normal amplifiers, the resistance must be raised by a transformer. So one way to identify a real ribbon tweeter is that it will always come with a transformer.  

AMT_diagram 

Air Motion Transducer tweeters, or AMT tweeters, work by creating a pleated polymer diaphragm that is vertically lined with conductive aluminum struts. This pleated or ‘folded’ diaphragm is set in a magnetic field, and when the aluminum struts are charged with alternating current, the folds expand and contract depending on the polarity of the current. The contraction of the folds shoots air out, and the expansion sucks air back in. A major advantage in this design is that since it is the folds of the diaphragm are much deeper than they are wide, the air is ejected out much faster speed than the vibration of the diaphragm itself- as much as five times faster. Much like a planar tweeter, AMTs do not need a transformer to step up the resistance of the circuit. They are pretty easy to discern the difference between true ribbons in that AMTs will have a wider pleated diaphragm surface instead of a thin metal strip; if it has folds, it’s an AMT. 

These tweeter types don’t have all that much in common. However, many loudspeaker manufacturers have decided to promote planar and AMT designs to the status of ribbon tweeters since ribbons are typically much more expensive and usually seen on higher-end loudspeakers. They are banking on the public’s ignorance of the differences of these designs versus that of the much more visually obvious difference between them and dome tweeters. The problem is that words have actual meaning, and it is dishonest to blur the difference. What is worse is that each has its own strengths, and Dr.Aplanar and AMTs can have advantages over ribbon tweeters. So, there is no shame in using planar or AMTs over ribbons, so long as the end design has good performance. While we are discussing this subject, domes, rings, and compressions drivers all have their strengths as well, so these flat plane diaphragms aren’t necessarily better than round ones; it’s all a matter of achieving a good performance target.

My recommendation to manufacturers is to just call AMT and planar tweeters what they are, and promote them for their respective strengths, which are considerable.

5.) Not All Sealed Loudspeakers are “Acoustic Suspension” (Almost None of Them Are)

There are many instances where loudspeaker manufacturers will label their sealed design as “acoustic suspension” or even brag about their high-fidelity “acoustic suspension” enclosure for more “accurate” or “tighter” bass. However, those designs are almost never true acoustic suspension designs, and they are almost always simple sealed loudspeakers. Our frequent contributor Steve Feinstein wrote a great article going into detail about the design and history of true acoustic suspension here: “Sealed is Not Acoustic Suspension in Loudspeakers,” so I won’t go into much detail here, since it is well worth reading his article. I will only briefly go over the definitions, so readers understand the difference- and why true acoustic suspension speakers are basically non-existent on the market today.

AR3a 

Acoustic Research AR-3a (1969)

Acoustic suspension has a lot to do with how the moving assembly within the driver is controlled so that it has a healthy level of excursion without needing a lot of power to move it. Acoustic suspension is defined as a speaker where the restoring force for the bass driver relies on the air pressure in the enclosure. In a typical driver in a typical speaker, the restoring force lies in the motor and suspension components. In an acoustic suspension system, air pressure forms a significant part of the restoring force and more specifically the back spring pressure from the interior of the speaker. That kind of system doesn’t need suspension with as much tension, so it can be driven quite easily. There is a whole other host of advantages that Steve goes over in his article. This design requires a delicate balance of enclosure volume and driver specifications that just isn’t how modern loudspeakers are engineered anymore, for better or worse. It’s a very different system than an ordinary sealed loudspeaker.

Editorial Note by Steve Feinstein:

Air is linear in its compression/expansion, much more so than a driver’s mechanical suspension. Acoustic Suspension proponents claim that this linearity can give AS systems lower distortion than other types, especially in lower-cost, small systems. A $100 ported bookshelf speaker with a garden-variety 6 ½” woofer likely won’t have the greatest mechanical linearity, but a properly designed AS system of the same size/cost will have cleaner bass/lower THD because of the air spring’s inherent linearity/regularity.

Dr.ASo why do loudspeaker companies still call their ordinary sealed design “acoustic suspension?” I would guess that the reason is pretty much simple ignorance layered with marketing gloss. Probably most people involved with the marketing and promotion of loudspeakers do not know what an actual acoustic suspension speaker is (not that being informed ever stopped marketing departments from twisting the truth). Many of these people would be too young to know about the original designs. And the misleading practice of calling simple sealed systems “acoustic suspension” has just carried over from decades past from those marketers who might have known the difference.

The solution to this is clear: just stop giving the label of acoustic suspension to sealed loudspeakers. It’s not like the phrase “acoustic suspension” has so much added dazzle since few people even know what it is anymore.

6.) Mounting Tweeters Away from Midrange/Mid-bass Drivers

One thing I would like to see change is having fewer speakers where the tweeter is mounted a significant distance from the adjacent driver in frequency bandwidth, whether that be a midrange driver or mid-bass driver. There are exceptions where this is an OK practice, such as when the tweeter can accommodate a low crossover frequency, but there are significant acoustic penalties for setting the tweeter distant from the next lowest range driver. The reason for this does take a bit of explanation, but when the tweeter is closer to the midrange/mid-bass driver, it can be a significant benefit to the speaker.

Vertical dispersion examples 

The reason why mounting the tweeter away from the midrange/mid-bass driver is a bad thing is that the areas in which the signals from those drivers integrate become much more narrow. The problem is that the sound wavelengths in normal crossover frequency ranges to the tweeter are very small, and if they are being emitted by two different sources that are spaced apart, they will conflict with each other everywhere where the distance between them is not the same. The further that the tweeter is from the midrange/mid-bass driver, the greater the potentially conflicting bandwidth a loudspeaker can have. Of course, this problem is contingent on the crossover frequency to the tweeter, and if a tweeter can have a low crossover frequency, that can do a lot to mitigate this problem. However, normal tweeters mounted flush on the speaker’s front baffle can’t usually handle a low crossover frequency. Most of them are crossed over between 2.5kHz to 3kHz. The wavelength of 2.5kHz is 5.4 inches. The distance of interest to us is the center of the drivers that have adjacent bandwidths, and this is called center-to-center spacing. We do not want the center-to-center spacing of the tweeter to the midrange/mid-bass to exceed one wavelength of any of the frequencies near the crossover frequency, and ideally, it should be a lot closer than that.

Polar map bad vertical response 

The result of widely spaced drivers is that the off-axis areas where the sound waves will conflict end up becoming deep nulls where output is totally canceled. These are called crossover nulls. This happens with any spacing between the drivers, but the further the drivers are mounted from each other, the worse it gets. When the drivers are close together, these crossover nulls occur further off-axis and can be less severe, but with a far spacing, the nulls can hang right around the on-axis angle, and that means that if you aren’t listening dead on the tweeter axis at a far enough distance, a big chunk of the sound will be gone because the sound from the tweeter is out of phase from the sound of the woofer. What is worse is that the frequency band where this usually occurs is an important part of the speech band, so this occurrence can negatively impact dialogue intelligibility.

Dr.AThis is why I always find it to be a matter of careless speaker design when I see the tweeter set a good distance from the midrange driver. What is also strange is that a lot of pricey “hi-fi” tweeters have large faceplates which necessitate a distant spacing. All that does is make the loudspeaker very picky about placement. If you are listening slightly above or below the tweeter height in such a speaker, you will be met with a big hole in the response and a noticeably incomplete sound. What is more, the vertical acoustic reflections are audible and can impact the sound, so a poor off-axis vertical response may adversely color the sound as well. If you are a loudspeaker manufacturer and have a tweeter mounted in a flat baffle, get it as close to the midrange as possible. It needlessly makes the speaker worse to put distance between them when it was possible not to.

7.) Packing Using Styrofoam

StyrofoamSerious home audio loudspeakers tend to be somewhat large and heavy. I would guess that the average bookshelf speaker is around 15 lbs., the average floor-standing speaker to be around 60 lbs, and an ordinary subwoofer to be around 50 lbs. Sure, there are examples of each that are lighter, but there are plenty of examples that are much heavier. Either way, since these items can be pricey, good packing is warranted due to the size and weight. Many Internet direct companies ship their loudspeakers in heavy-duty cardboard packed using thick polyethylene foam blocks of at least a 1” thickness or more. That is usually enough to protect the speakers through the major shipping carriers’ delivery (usually, but not always), and I would consider it the bare minimum. Many companies will double box the speakers and use extra thick foam blocks that cover the entire tops and bottoms of the speakers as well as a protective mid-section stand-off block. Sometimes shipping can be very abusive, and I have received speakers that were well-packed and still suffered shipping damage.

Once in a while, I receive a speaker that uses styrofoam for packing material. Usually, the styrofoam is broken if not completely shattered. On a couple of occasions, it failed to protect the product just through a single, one-way trip, and the product was damaged. It simply is not a good enough packing material for anything with significant weight. There is one famous loudspeaker manufacturer that is notorious for their poor packing practices that I won’t name (hint: starts with a K and rhymes with “lipsch”). The only speakers that styrofoam packing is adequate for are very light ones of less than 10 lbs., and even then a good amount of styrofoam is required to protect the items.

I get why some companies opt for styrofoam packing; it is much cheaper than polyethylene foam. A lot of people probably don’t realize the cost of safely shipping items like loudspeakers. It is a lot and constitutes a significant chunk of the price. Dr.AMaybe some accountant crunched some numbers and found that the cost of shipping-related damages did not outweigh the savings on using styrofoam packing, but that calculation ignores the feeling of disappointment of the end-user who was looking forward to the speakers. Furthermore, presentation matters, and it inspires more confidence in the buyers when they unbox their loudspeakers and see good packing materials. It means that the manufacturers consider their own products to be worth the extra expense and effort.

My recommendation: stop shipping anything over 10 lbs. using styrofoam packing!

8.) Sending Massive Subs and Speakers Through Parcel Shipping

Many high-performance subwoofers are necessarily large and heavy, since, as a matter of physics, it is very difficult to get deep bass out of a small enclosure (without tons of power, and even then, it is difficult). However, that complicates the logistics of moving them around inside the home and delivering them to the user’s home. Extra care must be taken to safely get them into place to avoid both personal injury and damage to the unit. No one should try lifting a 100 lbs. speaker or subwoofer alone, not just because of the weight, but because the size makes handling that weight very cumbersome. It takes a team effort to lift these things safely. But how often do you see parcel shipping delivery men work as a team? The answer is never.

parcel companies

Many parcel shipping services require their delivery people to handle absurd amounts of weight as a single individual. Sure, they will pay lip service by saying that they train their delivery personnel to use safe lifting techniques, but the reality is there is no way for a single person to safely tackle these packages -- yet the delivery drivers are expected to do just that. On too many occasions I have seen delivery drivers struggle to bring some massive box to my doorstep (and yes, I do try to help them when I know something big is coming). The only parcel shipping service that places a reasonable limit on the weight of their packages is the USPS, which only allows a max weight of 70 lbs. UPS and FedEx have 150 lbs. weight limits on packages that can be delivered through their services, and that is way too much for a single person. DHL’s weight limit varies by the type of service being used, but the most common ones that are used to transport audio goods are ‘Economy Select’ and ‘Express Worldwide’ which both have weight limits of 154 lbs.

Speaker manufacturers should be more cognizant of the realities of shipping practices, and if a large and heavy package is being shipped, it should be shipped on a pallet. Yes, it is more expensive, but if something is sent through shipping that is too large for a single person to safely handle, you can be assured that at some point, a single person will be asked to handle it. These individuals will either put their safety first and handle the item in a reckless manner, or they will put themselves at greater risk. I have known multiple individuals who worked for FedEx and UPS who ended up with chronic back problems. Yes, the people who work for these companies are supposed to always use safe lifting techniques along with the proper personal protective equipment, but with the kind of strenuous deliveries-per-hour requirements that these employees have to make, safety can go by the wayside in favor of job security. It is no mystery why all the major parcel shipping businesses have scores of labor complaints against them.

Dr.AMy recommendation to speaker and subwoofer manufacturers is that if the people in product development and management who are normal healthy adults have real problems safely liting one of their packaged products, they should have consideration for the logistics personnel that work in these parcel shipping companies and just send it on a pallet. It is the right thing to do. Shipping companies have repeatedly proven that they do not put their employees’ health and safety first. It’s unfortunate that responsibility has to fall on manufacturers and consumers, but it does. Pay the extra money to ship these huge items on a pallet out of consideration for your fellow humans.

9.) Plastic Tabs in Binding Posts

binding post tabs

Dr.ASome loudspeakers manufacturers put plastic inserts inside of the binding posts for some reason. They have to be removed before using banana plug terminators. In some cases removing these tabs can be annoyingly difficult. Harman is guilty of this, and I have seen this on Infinity and Revel speakers, but I have also seen this done in some non-Harman brands. Why do they do this? I can’t think of a single reason why this would have any benefit. Thankfully, it doesn’t seem to be very common. Nonetheless, it should be nonexistent. Loudspeaker manufacturers: stop wasting pennies on tabs for binding post inserts! You tell them, Gene!

Editorial Note by Steve Feinstein:

The reason for plastic tabs in binding posts is for CE (European) safety reasons. The ¾” binding post spacing is exactly the same as the spacing for the round spades on European AC cords. Plus, binding post holes will accept those round EU AC spades. Some brilliant bureaucrat somewhere thought that people were going to start plugging in toaster and TV AC plugs into speaker terminals. I don’t know for the life of me what they thought was going to happen, but that’s where those plugs originated—to prevent Euro AC plugs from being connected to speaker terminals. The reason for their inclusion in North American loudspeakers: in addition to the above, it’s so U.S. speaker companies don’t have to build and inventory “domestic” and “European” speaker inventory. They build one variant and ship it wherever.

10.) Sealed Configurations on Large Ported Subwoofers

Many manufacturers of high-performance ported subwoofers have decided to include the option for running the subwoofers in a sealed operating mode by including port plugs as an accessory. The question I have is why? Why would anyone buy a giant ported subwoofer but then decide not to take advantage of the very thing that makes that huge size a necessity (their super-deep bass extension)? The reason why those ported subs must be so large is so that the enclosure volume can support the very low port tuning frequencies. In other words, a big box makes deeper boom boom. Sealing the ports completely negates the ability of the ported sub to produce big SPLs in low frequencies, and so it negates the reason for the enclosure size to start with.

1961V port plug

The only reason why sealing ports of a ported subwoofer could be useful is in a small room that gets so much acoustic low-frequency gain (this is called ‘pressure vessel gain’) that it massively blows up the low-end of the in-room frequency response and produces a boomy or bloated bass sound.  However, a better method of tempering the deep bass is to simply EQ the response. That way you can get a nice in-room response without losing the headroom that is granted by the ports. Many of these subs come equipped with onboard ways of electronically reducing deep bass output, as opposed to the physical method of closing a port. And the likelihood of someone placing these huge subs in a small room is low- and if they do, they probably want that excess deep bass.

Dr.AIt seems to me that subwoofer manufacturers do this because the foam inserts are cheap to include as an accessory and the manufacturers can then claim more operating modes in the checklist of the subwoofer’s features. But what is likely to occur is that those who don’t know any better may simply leave the inserts in the port and run the sub like that unknowingly eliminating most of the sub’s deep bass output capability. In other words, it is more likely to be a source of confusion and thus suboptimal system setup. It just shouldn’t be done, as there is very little benefit to this ‘feature.’ My recommendation to subwoofer manufacturers: don’t bother with the inclusion of a sealed operating mode in your ported subwoofers. The reality is that it doesn’t do any good. 

Conclusion

These are a few of the things that loudspeaker manufacturers are doing that I wish would change. Some of them are worse than others, and this isn’t even a complete list of the practices that ought to stop. I just figured that 10 is a nice round number and kept it at that. Stay tuned to Audioholics for more rants in the future just like this one!

Too bad the courier/parcel express companies raised the weight limits significantly over the years, not fair to the driver or the package….

Great article. Love reading things like this

Harmon is the worst on their packaging especially their Infinity speakers. They are messed up a LOT. Their JBL 590s are a little better as they come freight on a pallet

I end up biting the bulled and putting the SVS feed on all my subs. I know many think it's a waste but if it's a sub we will use for years it's not too big a deal

On FEDEX/UPS, my nightmare on that was related to a Outlaw AMP I bought used from someone. It's a heavy AMP. I looked out the window and saw the UPS driver literally rolling the box to the door. It did some damage but still worked. I really like when companies send heavy stuff via freight on a pallet but I know that adds cost.

We could write a whole article about the shipping issues, alone!

I do like international companies (Buchardt, Arendal) that include shipping and all customs/brokerage in their pricing. But then you have domestic companies (SVS in particular) that includes shipping (+all of the cost of their customer bill of rights) in the pricing of each of their Speakers.
For SVS, while convenient, it skews wildly the perception of value, I think. How many posts have we had where potential owners are comparing Hsu Subs to SVS, then hem and haw over the shipping charges from Hsu? Or the reverse about the cost of a Sub from SVS?
To be fair, the international shipping is much more of a pain to the uninitiated than dealing with anything domestic. That, and the fact that it is way more difficult to return gear internationally is why I think that it is better applied to those companies rather than domestic service.

Rythmik used to offer a UPS Freight service for their larger Subs that gave you the option of picking them up at the Freight Depot for a discounted shipping cost. I'd bribe a friend any day with a good six pack and a pizza to hop in their truck and go get my gear with me! Hell, even a cheap U-Haul plus the cost of bribing a friend would be worthwhile.

That said, fright delivery is definitely the way to go. I know from a previous conversation with Jim Salk that shipping FedEx just got too expensive due to damages, and (at least for a while) he sent everything large, on pallet, through Roadrunner.
I mentioned above getting my Phil3s delivered. It was super easy and even with the transfer to a local freight company for the final delivery, everything was smooth. The biggest thing for me was just making certain that the freight company making final delivery knew that they couldn't send a full size truck. The guy pulled in and I helped him offload through the side door, and much like my earlier description of receiving my Subs, the driver helped me get the boxes just inside my front door.

Lastly, I know that everybody loves a sale, but my favorite aspect of my previous purchases with Outlaw was that they paid the freight on my 2018 holiday season purchases! I think more companies should look at Free Shipping sales rather than discounting the product. In all honesty, my gear from Outlaw was both discounted and shipped free.
But how can companies move forward in light of the completely borked system right now? Prices are up for everything from the smallest component the manufacturer buys to the cost of shipping the already more expensive final product to the end user.

We might all hope to just get our product delivered in a timely manner, and without damage, now. Sh!t, now that I look at that, we might just be glad to be able to get something, Anything!, even if its delivered broken considering the supply chain issues.

Great write up, Thanks! I had quite a few bad experiences with shipping so now I would only go pick them up myself if possible. Thank god I do not have to upgrade my 12 year olds.

Regarding #10 (port plugs), I like the variable tuning options provided by my Hsu port plugs.
Variable tuned isn't the same as sealing the sub completely. But I do think variable-tuned subs is where all this madness started.
