The way my den is laid out, people have to walk around my RPTV and one of my front speakers to get to the seating area. My fronts are on normal elevated speaker stands and the dog has come close to knocking over the right front on numerous occasions and has succeeded twice. I want to build a cabinet that encompasses my 40H80 Toshiba (40") and will hold my front surrounds and center channel speakers. What I am concerned about is reverberations and boominess and what not from the speakers. Can anyone offer any tips on how to build something like this so as to sonically isolate the speakers from the cabinet itself? I'm not much of a speaker expert so I hope this all makes sense. Thanks in advance!
