Room Modes and Dealing with ThemWhen the boundaries of a room accentuate bas frequencies, the listener's perception is one of a reduced midrange and soundstage. If you don't get the bass right, nothing ever comes together very well. |
EMP ECA-4 & ECA-44 Compact Satellite Speaker System ReviewThis is a must have solution for any application requiring a compact clutter free and inconspicuously mounted installation. For a limited time, EMP is extending 50% off their MSRP which makes this system even more attractive and a very uncommon value. So basically $500 gets you 5 high performance compact satellite speakers. I recommend pairing this system with two small but potent subs and you’ve got a “cubed speaker system” killer for under $1k. |

Many people think that the secret to a great home theater is great gear. And when you ask them what that gear consists of, it will usually be a display, speakers, components, and cables. But the ingredient that can often make or break a home theater is the room itself. My room is an excellent case in point, which is why I chose to bring in the good folks at Auralex.
Tech Article: Velodyne Mic-5 Add-on Supplementary Review

The proprietary Velodyne subwoofer correction system is included in all the higher end Velodyne subs as well as a standalone unit called the SMS-1. Anyone that has done much research about subwoofers has undoubtedly run across the SMS-1. A 1/3 octave smoothed, on-screen graph in real time makes adjusting and parametric eq’ing a subwoofer an exercise even the most technologically challenged can excel at. There are very few additions to a full surround system that have the impact of a room correction system. You’ll wonder how you ever got along without it. And with the addition of the Mic-5, you now have the ability to correct for multiple seating positions creating a better experience for everyone. While the Mic-5 add-on may be a bit pricy for the average consumer, I can see it as a very good investment for an installer or perhaps a group of friends that can split the cost. It is nice to be able to correct for a sweet spot, but multiple seats takes it to a whole other level.

Ultimate audio performance within the listening area starts with the loudspeakers and the room. How the Installer gets the loudspeaker system to integrate within the listening space is what can make or break even the best assembled audio systems. In our article Better Sound Through Active Room Correction (recommended reading before reading this review) the important metrics of loudspeaker placement and selection, room acoustics, and how to best integrate all of these variables using the new Audyssey Pro MultEQ enabled processor for the ultimate theatrical experience in the comforts of your home was discussed. We now expand upon this with a formal review of the Audyssey MultEQ Pro sound equalization processor.
Pro Review: Onix Rocket Digital Equalization System (R-DES)

Being an official Audioholic comes with a couple of drawbacks. The first of which is that you are required by Audioholic charter not to believe in many of the tweaks out there. Magic rocks, cable risers, wooden volume knobs, batteries anywhere in your system but in your remote… What is a bona fide Audioholic to do? Well, after treating your room, the next “tweak” is an EQ for your sub. At least it is for me. I’ve wanted one of these for a long, long time. When Clint mentioned in passing that he needed someone to review the Onix R-DES, I practically tackled him.
Pro Review: Auralex MoPADs Monitor Isolation Review

In an ideal world there would be no war, disease or hunger and our loudspeakers would be perfectly placed in perfect rooms for perfect sound. While Auralex probably can’t help resolve world issues, they certainly can help with speaker placement, room acoustics and isolation as evident by their isolation pad devices they refer to as MoPADs and the up and coming new acoustically treated room for the Audioholics Showcase home premier reference system.
Pro Review: Velodyne SMS-1 Subwoofer Parametric EQ System
by Clint DeBoer — last modified April 09, 2006 20:00

We were introduced to the Velodyne SMS-1 system at the CEDIA show in Indianapolis last year and were instantly impressed with its potential for improving how subwoofers interact with the room. The SMS-1 is basically Velodyne’s flagship Digital Drive room correction software offloaded into a standalone system that allows it to be used with any (even *gasp* non-Velodyne) subwoofers. The SMS-1 is essentially an 8-band parametric EQ with variable frequency, Q, and gain that shows you a real-time smoothed graph of the room’s low frequency response from 15Hz to 200Hz via an on-screen display.

As Audioholics, our pursuit of audio perfection seems never ending. We are always on the lookout for that next piece of gear that will improve our system. Many of us will spend our budgets dry and drive our significant others to the brink of the funny farm in this continuing journey. With all of this madness, however, the one area many of us overlook that can have significant impact in our system is room acoustics.

Tom Holman had a problem. As Professor of Film Sound at the University of Southern California's School of Cinema-Television, one of Tom's duties was to set-up, calibrate and acoustically equalize Norris Theater. This minimum five hour job was a step-by-laborious-step of set-up and reconfirmation of settings done months before. Inevitably, recalibration accompanied by more fine-turning was always required to make each channel of the Norris Theater system perform optimally. Norris was but one of literally tens of theaters and studio facilities that Tom has been calibrating manually for many years.
