Good like finding a 200uF poly cap that is of reasonable size and cost that can fit in the crossover. Bypassing electrolytics is a great compromise to this problem as most manufacturers tend to do. They placed two 400uF 100V caps in series which halves the total capacitance, but doubles the working voltage to accommodate high power amps without blowing up. The bypass cap is a very high end Solen which again isn't clear in the photo.
The choke on the woofer is a 6 mH low DCR and has a power rating of 500 Watts with low saturation so again you simply apply a absolute that all iron cores must be bad.
For midrange drivers and tweeters I tend to agree but using them for bass drivers where the values often get large are an understandble application. A choke this value in an air core would be much larger and have more resistive losses thus you would lose damping which is critical for the bass frequencies. So if the steel core isn't distorting or saturating, then why change it to something costlier, larger and potentially less performing?
He was implying that a passive crossover this low is a no-no, period. That you should either go active or cross much higher in a 3-way.
Every listening session I have heard on these speakers is far from sloppy bass.
Yes, but your perception of sloppy bass may be a bit different from TLS guy, who finds that only critically damped transmission lines etc can really reproduce real life instruments of classical music. You seem to prefer a bit more punch...or dare-I-say-it.. bass coloration compared to the "dry bass" he prefers and certainly seem to have a different taste in music...
My T30-LSE towers for example utilize no passive crossover at all in the bass drivers and this is from the same company. It all depends on the product design and how well the system plays as a whole. Every design is different and you have to do what is right for that particular application.
His complaint was about the application itself... a very low crossed passive crossover.
Looks like they're afraid to get a fair review
I kind'o always wanted statement speakers, and the RBH Sound Signature Reference 8300-SE/R looks like a quite fair bet
Looks like AcuDefTechGuy has a pair of the BP7000SCs. Maybe he'd be willing to lend them to the cause.
Just send Gene yours since DefTec won't.
Yeah, that would be right after I get some flagship RBH or B&W 800Ds.
yes I even called their Marketing Manager to offer him to enter his product in Tom's floorstading speaker faceoff and he declined saying nobody wins in a faceoff but the speaker that got 1st place. He also said we tend to nit pick too much about product performance and rely too much on how things measure.
Im sorry Gene, but are you sure you didnt call the Bose marketing department?
That sounds like a line right out of their play book!
