What the OP means, I think, instead of "Bare Minimum" is "Where will treatment do the most good". Lets take a look at what room treatments purpose is to begin with. While there are always dissenters, most would agree that even decay across the entire audible range would be the ultimate...

I agree, corner placement is bad. But if your stuck with it, filling in the corner with absorbent, floor to ceiling, as far out as possible (greatest depth), will help some.

:thumbs up: Your never going to get a satisfactory answer when your asking the wrong question.

I don't accept it because its not true.

Your argument seems to be that we need test results of how a bicycle tire on a dragster will perform to confirm it wont work very well. Every paper and valued opinion on absorption that I have ever read specifies that absorption should be broadband. Given thin foam (most foam in general) is...

Our point, or my point specifically, is that if you understand the properties of how the material in question performs, then you dont need a room fully treated with it to know how such a room is going to measure in regards to the effect the material will have.

Firstly, a well treated room typically employs absorption, diffusion, and redirection. Not absorption alone. All one really needs to know about absorption is what frequencies it affects. Thinner, denser materials are only going to absorb higher frequencies where thicker lower density...

Just a pointer, R19, when thick (12"-18") does WAY more absorption in the bass region than 703 can do at any thickness.

So I know what page your on, what data are you looking at in your comment? For whats its worth, any room decent size room with decent dimension ratios can get this flat. Just a matter of treatment. If you were to post your data, and your room specs, bet it can be improved.

Changed a couple things, and now this. Hmmm. Not sure I trust these measurements. In any case, better looking graph :guitar: mdat: http://www.gearslutz.com/board/10285285-post388.html

For what exactly?

JHB, I guess my real question for you is whether there is anything here to really be concerned about. The right channel (red) doesnt behave as nicely as the left channel. The areas around 63hz and 630hz are a bit off id say. Despite the data, I just dont know whether to put much validly in...

My latest mdats can be found on the last post at this link My Listening Room - Page 13 - Gearslutz.com The interior walls are 3/8" (thin) sheetrock. No insulation in between. :( On one side of the 185" dimension, to the R of the R speaker, a big section of the wall (which was once an...

Hello JHB I see many here that frequent other sites. Anyway, was curious about your RT60 criteria. (all channels and subs driven) My room is 8.25'H, 15.5'W. 25.75'D (but with lots of caveats) Yes, we have spoken before :D I was especially interested in your comments regarding limp mass...
