I am currently planning out acoustic treatments for my semi-dedicated HT.

My 128" CIH screen has forced me to place my L/R speaker within 12" of the side wall. I am going to treat this area and was thinking of going with 4" panels.

Will this be an issue or do the panels essentially remove the boundary effect of the wall?

Thanks

I think you're making a good choice.

So your saying there is no issue having speakers 6 to 8" from the acoustic panels?

The distance between the loudspeaker and the treatment is not relevant to any consideration I've ever heard of - assuming the treatment isn't in front or something, obviously.

The distances that matter are the distance from the speaker to the natural boundary (wall, etc.) and the thickness of the treatment. The distance between the speaker and the wall determines (basically) the frequency of the null created by the interference of the reflected sound. The thickness of the treatment should be adequate to absorb as much of the sound energy at that frequency as possible. Without doing all the math, and making a judgement call based on my own inexperience, I think you're okay.

Ok. Thanks. The more I research on room treatments the more things I uncover that I didn't even think would play a roll. I just want to make sure I'm not missing something.
