That is one of many characteristics/issues with coaxial drivers. Thermal compression is another which I've found myself most sensitive too when listening to these type of speakers.

Dr. Toole isn't the first to write about the benefit of early reflections on speech intelligiblity in small rooms. Many others have done similar, though not to his level of thoroughness, in the past. Here is one example...

I am not sure I can let the cat out of the bag until CEDIA but lets just say for those who like to tweak stuff to the nth level and have the right tools to measure before and after results, you're gonna love the upgrades :)

Room modes that are much larger in amplitude than room noise behave in a minimum phase manner. The more it is attenuated or corrected in amplitude, the less problematic and inaudible they become. Again the one cubic inch argument has little relevance at low frequencies as bass doesn’t...

You deserve to be made aware of your obvious biases and agenda to promote the only solution you know which you incidentally sell on your website. The problem is you promote a lot of misinformation which puts me in a predicament on whether or not allow you to spread misinformation on our forums...

Measurement of Audioholics Showcase Room (6 Position AVG) Attached is an averaged response for the primary listening area (6 seats) for the left front speaker with all 4 subs playing. This is before I did some more tweaking last night to flatten the bass response in the 20-40Hz range. I...

No the reality is you spend alot of time online promoting the only solution you know/offer - your Real Trap product. My measurements are 1/12th octave averaged over 6 listening positions. Then you haven't looked very far. Dr. Toole has authored plenty of papers on the topic as have we. I...

The key ingredient is selecting very linear loudspeakers! My room is passively treated (but not over treated) by Auralex. The response I am measuring is from one main speaker at a time for all 4 subs playing. Its an averaged response of all 6 listening positions. Audyssey EQ actually helps...

Parasound makes solid amps.

Oh geez! If you flatten bass response in the frequency domain, you reduce the ringing. If you never heard a correctly implemented multi sub system, you don't know what you're missing. I have almost no passive treatment in my room for bass yet I am achieving +-5dB response from 20Hz to...

Just so you know, those aren't continous ACD ratings. They use a class H type topology which modulates the rail voltage depending on input signal. Its more efficient than traditional linear a/b's and slightly more than Class G. The penalty is however a higher noise floor which can be an issue...

You should really read Dr. Toole's latest contribution to AES on acoustics in small rooms. In it he makes a strong argument for NOT treating first reflections with absorption if you use speakers with uniform on/off axis response and constant directivity. I can see how a compromise can be made...

Be careful with overtreating your room. Dr. Toole just released a new paper to AES on acoustics in small rooms where he proves there are benefits in vocal intelligability from early reflections. Overtreating the first reflection points could be responsible for your dislikened vocal response in...

Yes that works but I also told her I need to play it this loud to break in all the woofers :) Cool, though it may be a # of years before I head out that way again. I am really into Pesto sauce for Pizza lately. My wife makes a killer pie using Pesto as the sauce, fresh tomatoes, spinach...

The only advantage of having a 20A circuit is so you can plug more stuff into it without tripping the breaker as easily. You will not be able to deliver more power to one device such as your amp, but instead have the ability to connect more devices to the same outlet.

That is a good article with great references to UL and OSHA but the author is way off assuming a Linear A/B amp will deliver 70% efficiency #s for power. The best case scenario is more likely around 50-55%. Again, the power spec listed in that review is ACD for instantaneous NOT continuous...

Roly, the article link below should clear up most of your issues regarding power ratings in amplifiers. http://www.audioholics.com/techtips/audioprinciples/amplifiers/ACDTEST.php

I am in the process now. I achieved pretty good results until I brought my home theater chairs in the room. Now I have to do a recal and new measurements. I am also testing their stand alone unit cascaded for the sub channel with the one built into the 5805. I will be generating a full...
