I am about to install 18 11" round Polk LCi80 InWall speakers, and would appreciate any recommendations as to which damping material to use. I saw a product called AcoustaStuf in Parts Express, but the cost is very high...($35 for 5 pounds, which they note would cover a total of ten cubic feet).


Would polyfill or fiberglass work as well, or is there some other substance which would do the job. The speakers are high end, and the wall construction is typically modern sheetrock/studs.


Also, would placing a sheet of foam right behind each in wall, be recommended (to prevent any fill from getting into the speakers)?


Thanks in advance for any suggestions..

Hi,

I had the same question, since I have a 7.1 set of Jamo inwalls I called them and asked the same question and according to the engineer regular fiberglass is what is used in their test labs and it is fine to just push the speakers in the wall like that, although I could not see myself pushing the speakers into the fiberglass so I just some fiberglass window screen between the speaker and the fiberglass insulation and have not had a problem yet.

Thanks much for the reply. On my current inwalls, I have been using fiberglass as well, and was curious if there was something "better" out there, at a reasonable cost (pilllow fill, or "polyfil" was another product I was considering, as it is widely available...don't know if it is better or not though).


Also, I have heard that there was "acoustical fiberglass" sold, but never actually saw it at any supplier.


As far as the back of the speaker, your idea sounds like it will work fine.


Best Regards,

Harris
