Hello there....... I have searced and read many of the recommendation on this forum, but I guess every situation is different. So I figured I would ask for opinions. New construction of house still on-going, no drywall up yet. I am placing in-ceiling speakers in the ceiling of the living room and there is a bedroom above. The second floor uses the TGI flooring system so I have long deep spaces between the floor joist and there is no plan to insulate the entire ceiling. I have found many suggests on how to soundproof/insulate around in-ceiling speakers on this forum. I want to do something on the cheap side as some of the recommend solutions are expensive. I was thinking about just getting some pink foam board and constructing a 3 sided box where the speakers will be placed then lining it with some R13 insulation. Would that provide some general soundproofing????
