ARS can absorb down to 100hz because the wallboard lined 1" panels act as a membrane absorber when the hard side is out. 1" fiberglass dips down to around 1k (a little lower when the angle of incidence of the sound wave is more acute). So, with the big, stuffed Cineak Stratos, the carpet, and the fabric over the front of the 1.25" deep ARS diffusors, I'm guessing that the RT60 of that room is somewhere in the area of .08-.15 seconds.
you see, I'm not criticizing YOU, I'm stating that the acoustic treatment is a compromise; it could be different, but you'd have to give something else up- thus compromise. YOU needed to fit a *****load of Quested (or was it PHC that time?) into the room with an enormous screen (neither of which I argue with at all!)- but to say that you don't have to have a room maintain acoustic spaciousness anymore because of the loudspeaker count is just not true. You can mitigate the closed-in feeling of an over-damped room through the use of the playback system, but only if you're using multichannel processing like Trinnov and, by the way- that still doesn't mean you SHOULD always. It still doesn't make the room
spacious sounding- just the playback system.
And anyone can search my posts to view my opinions of technologies that include the use of many loudspeakers (Trinnov, etc.) A room is spacious sounding or not regardless of the loudspeakers. Spacious sounding rooms are preferable to humans naturally (notice I did not say echo-filled or reverberant or even large), so it is logical to say that a spacious sounding room would still be preferable in the case of advanced playback systems and audio signal processing.
The point of my argument is that a room that is treated to sound real and spacious (like standing in the middle of the woods- to quote Matts) sounds that way whether there is only 1 source of sound or 1000 sources. Anything else is contrived spaciousness utilizing the playback system.
I've been using extra loudspeakers and outboard dsp to generate the same contrived spaciousness in rooms that can't get proper treatment for years (think family room or something not purpose-built). It doesn't make it any less of a compromise.
So, quit getting all worked-up and drop the juvenile name-calling.
ARS is a compromise in acoustical treatment, so is just using Auralex foam or 6pcf fiberglass panels. That's it, better solutions are available, and if someone asks the question, they deserve to hear that there ARE better solutions available. That WAS the original intent for the thread, after all- to ask if 2" or thereabouts constitutes acoustical treatment of a room.
You are free to feel differently than I do, but please don't insinuate that my knowledge or experience is lacking just because I don't post images, etc of the work I've done.
We're having a technical discussion here, not a mud-slinging contest.
