Acoustic TReatments - What, How much, & Where?


Hello all you room treatmentfiles.

Being at the point where I probably should have begun, now, I want to 'treat' the room, acoustically. Economic reasons say I might have to go by way of ‘foam’ stick ups on the wall, but I’d really rather not. The desired alternative, however, is panels, and they are mighty pricey. OK.

Reading over the online info at various panel makers websites, (ASC, RPG, GIK, etc), some panels have different ranges of absorbtion, reflection, etc. according to the makers.

Q: How do you know just the amount of absorbtion, or diffusion to incorporate into the room via panels, traps, etc.?

Is there some Rosetta stone that will decrypt this for me… or is it all “trial & ear-ror”?

GIK panels seem the most feasible cost alternative, presently.

Any suggestions or related experiences in regard to sources for, or treatments of, will be more than a welcome thing.

Thank you
blindjim

Newbee, i am no expert but i thought toe in reduces the soundstage width? In my room, as I decreased toe in I found the soundstage to increase width wise tremendously. Am i missing something.

THANK YOU...very informative. May I ask what test cd you use? Are the ones offered by Chesky any good? If so, which one?

I am in your same position. I have been researching acoustic treatments for almost 6 months now. My biggest problem is that most treatments are pretty unsightly. I am not lucky enought to have a dedicated listening room. Instead I converted my living room into a music parlor with our grand piano and various guitars. This means that appearances is a very important consideration. Only recently have I made up my mind about which treatments to use. I know the products I chose are probably not the best but i think they offer the best compromise between performance and looks. Anyway, here is what I am going to use:

Eighth Nerve tri-corner and corner treatments (these are VERY small and inobtrusive)
GIK corner bass trap (these fit very nicely into a corner and can be used as a platform for decorations)
Acoustics First Sonora panels in custom sizes for 1st reflection points and wall behind speakers (with custom sizes I can design something artsy on the walls).

I estimate I will spend < $1500 for all of this. I hope this helps.

Everyone else, please feel free to let me know if I am missing something or if I am smokin' crack!
