I put in-wall speakers into a small room which has hardwood (masonite) panels mounted on studs. Obviously not ideal, but cheap and it was not my work. Now I need to replace the panels as I'm moving. Would it wise to just remove the entire panel where the speaker cut-outs are and replace each one? I'm thinking that any kind of patch work on the massive 6-1/2" x 3" rectangular holes would be near impossible to seal up on this material.
