I am currently woking on my home theater and almost have completed putting my drywall up. I am curious what I should do to the walls after drywall? I have seen several posts regarding GOM fabric and Insulshield, are these the items I should be looking at? I also saw some info on putting the insulshield on part of the walls, and something else on the rest? Basically my monitor is a 65" toshiba RPTV, and I have Def Tech speakers L/R/C/LR/RR. Any help that I can get in making this important decision would be greatly appreciated! Thanks!
