I have a 9.2.6 system in a 16x25x9 home theatre. Long story short I have a front wall with left, center, and right channels and these are surrounded and backed by 15-25" of insulation. See the photo below. A screen goes in front of the speakers. The insulation was placed based on the following assumptions:
1. Reflections off the front wall in a home theatre are generally bad (correct, I think).
2. Materials that only absorb high end frequencies are problematic as they disproportionality impact the high end. Therefore, thicker materials that absorb lower frequencies are preferred (correct, I think).
3. I had tons of material (true), so why not
4. "baffle" walls for home theatres are a common thing so surrounding speakers with insulation can't be that bad (don't know if correct)
5. The majority of sound from speakers comes from the front, so having insulation behind or around them isn't a big deal (don't know if correct)
FYI the subwoofer is ported and the driver and ports are facing the center speaker in that gap.
I'm wondering if I messed up here with this system.
Is placing insulation so close to my speakers a problem? Should I just remove a lot of it to free space?
How does insulation so close to speakers effect frequency response and dispersion or other qualities? Data from actual measurements would be especially helpful!
