By all means, this is why we write this stuff :)

It is actually an L shaped room since the bottom right portion is my closed in office which measures roughly 10' x 8'. Thus the theater portion of the room is 28' long by 15.7' wide. The seated area is 15.7' wide by 10' deep. The right front speaker will be about 12' off the right...

Don't waste an amp on just a tweeter. Run the top mid/tweet portion off your receiver and use the internal amp for the side firing woofers. Save the extra 2 amps in your receiver for the EX channels. If you aren't taking advantage of PLIIx, you should be!

This is a bogus statement. It would only be true if you were running continuous sine wave test tones into a resistive load for all channels at the same time and then it would only be true for the lower end Yamaha and Denon models whose power supplies cannot deliver all of the power from the...

I have the new Audyssey firmware but my reference speakers are still being built. Thus the delay is all on me at this point and NOT Denon. I am hoping RBH will have my new speakers built by next month so I can continue forward with this testing. If it takes much longer than that, I will pull...

I do have a system in a relatively bad room which opens to my whole downstairs floor. I am using a Velodyne SMS-1 to bass manage my sub and reduce modal peaks in the primary listening area. Of course it does next to nothing for all other seats unfortunately, which is why I am going to be...

It is usually NOT possible to sit the listeners equadistant from all speakers. Don't you agree that time alignment in the processor takes care of this problem? As for spatial averaging in the primary listening positions to look for system pathologies, Do you apply any weighing to those...

Your "expert" clearly wasn't expert. Trying to fill cancellation holes will INEVITABLY lead to problems. That is one of the first thing real experts learn, from experience if not from theory. You Don't BOOST NULLS! And at low frequencies, where wavelengths are very long (about 22 feet at 50...

What measurement tool were you using? Did you have the exact same subwoofer and mic placement for each measurement? Moving a sub / mic even a few inches will affect your response.

Even more sad when they dump $1000's on cables as a promised cure all for their sound problems :D

Glenn you should do some reading on this topic if you haven't already. I suggest some of the white papers on Harman's website and some of their contributions to AES. I never said there is no need to treat a room but the benefits of multiple subs for increased modal control over a wider...

You are incorrect about EQ or more relevantly used minimum phase PEQ’s NOT reducing ringing. Low-frequency room resonances behave as minimum-phase phenomena (Dr. Toole recently authored a paper on this that he submitted to AES). According to Dr. Toole, a parametric equalizer that matches...

Using multiple even # of subs (ie. 2 or 4) correctly positioned also works wonders in creating a wider and more consistent listening area of smooth bass response. This is a technique most competent installers are using today which is also championed by the likes of Dr. Toole from Harman, THX...

HAA (Home Acoustics Alliance) is one of a select few organizations we endorse as authoritive experts in the field of acoustics. They offer training courses to dealers, installers and consumers in efforts to help improve system integration and education of sound acoustical principles.

Actually you will likely achieve better results EQing just one of the subs and running the others in Bypass. I don't recommend applying one global EQ to all 3 subs, especially since they are likely located at different path distances from the listening area. BTW, you are better off with 2 or...

That’s a rather bold and inaccurate assessment of Tony’s article, especially since he is such a noted Acoustician in the industry. Tony’s article is in fact correct. He is referring to panels mounted on a wall. Since in your application, you are mounting the panels diagonally across a...

They don't, at least NOT effectively or predictably. While corner traps will provide at least something, this is why you want to construct bass traps and resonators which are far more involving than a 4" panel if you are serious about room correction. More to follow on this later.
