I have been looking around in the forum and i haven't found what i am looking for. I haven't decided on a in-wall center speaker yet haven't even really started looking. But i am putting up the drywall and before i do i need to modify my front wall so i don't have a 2x4 right where my center speaker will go. But what i need to know how big should i make the rough opening so that when it comes time to drop a speaker in it will more that likely fit in the space i framed in.
Currently I have 4 Polk Audio RC85I 2 RC80I and a PSW505 sub.
