    Hello. I've had a home theater in a box for quite some time. I recently decided to rebuild my speaker enclosures to give them a more solid look. When I disassembled the old ones, there was a strip of insulation glued to the inside walls of each speaker. I am curious as to the purpose of this insulation and what would be considered a good replacement, or if it is even necessary at all. I believe it would be some sort of sound dampener, but it is just a guess. The enclosures in question are the center channel and the surround speakers. Any help would be greatly appreciated. I am holding off sealing the speakers until this issue is resolved. Thanks for reading everyone.

    Sound dampening is probably the main reason, otherwise the speaker could sound a bit on the hollow side. Plus, consider, manufacturers wouldn't put the stuff in there (costing them money) if they didn't think it helped with the sound quality.
