All, I'm not building my own theater (yet!), but I'd like to get some input on something I ran across recently. I see talk of soundproofing, but very little of its downsides, except the extra headache to achieve it. The best way for me to explain this is to link to what I read. Start here, particularly the comments in paragraph 4: https://www.avsforum.com/forum/19-d...-required-2017-home-theater.html#post50684857 And this post on the following page: https://www.avsforum.com/forum/19-d...equired-2017-home-theater-2.html#post51003913 What I take away from that is, a well-sealed room can be very problematic for bass, and one that "leaks" more would generally have less ringing/faster decay and smoother response. What do you guys think?
