Bose may have done this, but that wasn't the speaker system I was thinking of... It was the same brand that makes those speakers that have combination drivers. That's not the right word....tweeters and mids share the same driver, whatever that is. I think John B or Chess owns a set. At any rate, that's the brand who made them. I think they were about 5K each. I didn't spend much time looking at them.....

Revel Loud Speakers have always had some fashion of tuning in their high end speakers. It's more trim controls to compensate for near wall boundary gain, and/or highly reflective surfaces. They're $22k for a pair, but it shows that some manufacturers will allow the sound of their speakers to be altered to compensate for placement/room issues.

Well yes, but THEY are doing it, not IT being done to them by another company's widget. Big difference.

I'll keep quiet on this from here out and in retrospect, shouldn't have said anything. I shouldn't be speaking for Axiom as if I actually know my ass from a hole in the ground.

I don't believe Axiom (Alan as commented in the past) recommends room treatments, other than natural room furniture, etc.. Personally, room treatments (corner bass traps, and first reflection panels) as used in recording studios should also be used in a HT environment, for the same reasons. You don't want to over deaden a room, but there are tons more scientific studies from reputable audio labs to the benefits of adding these, compared to the few NRC tests to the contrary. Even Kris K and Tomlinson Holman (THX founder) from Audyssey say they should be included in addition to proper room room eq like Audyssey.

I can vouch to the huge benefits Audyssey has done for my home theater, with Axiom neutral speakers, and it has not made "good speakers sound worse", as is often said on here...

Audyssey adjusts for different room characteristics at multiple seating locations. Speakers designed to be neutral or flat in an anechoic chamber is one thing, but as soon as you move them into the various rooms we all have, products such as Audyssey are needed.

I would think it would be more of a personal preference more so than " products such as Audyssey are needed."

All you have to do is press the button on the remote to jump from before AND after. I'm guessing your ears will say, crap, Audyssey is awesome.

If the ears start talking, who's going to listen to them?

Not sure if Alan still stands by this but here’s what he has said emphasis mine:

Auto-Setup and Calibration

Even inexpensive AV receivers now have some type of auto-setup mode, with many including a supplied microphone and auto-calibration/equalization circuit (Audyssey is very common) that claims to adjust the frequency response of the system’s speakers to match the room’s characteristics.
While the auto-setup modes are initially useful for first-timers, they are still prone to error, sometimes setting speakers that are small to “Large” and making errors in speaker level settings of 4 dB or more. You should still do a manual check using a sound-level meter and a pink-noise signal.
Unless you have really poor speakers, I recommend you turn off the auto-EQ circuits. They may help smooth out the non-linear spikey frequency response of poorly designed speakers, but with really smooth linear speakers like Axioms, they often degrade sound quality.


Here is what Alan has said about room treatments:

That room acoustics article makes me want to put Alan's signature on everything.
