Attaching a frame to an existing wall for soundproofing.

Hi! First time building a frame here :) I am planning on building a frame to attach to an existing wall. I intend to fill this wall with UltraTouch Denim insulation, covered by mass-loaded vinyl (MLV), and then finish it with acoustic wooden slats (from wood veneer hub). This wall must support 2 20lb speakers on steel mounting plates that reach 14 inches away from the wall (torquey) and then a TV (40lbs) flush mounted in the middle. I was considering tearing down the drywall of the existing wall and replacing the spray foam insulation, but that just seems like a massive hassle. I'd rather just lose the 4-5 inches and attach directly. I am also considering just mounting the wall like this but that just doesn't look like it would be suited for load bearing installations. Would this wall still be strong if I connect it to the floor and truss of the room? Or will I be compromising the integrity of the wall by connecting to drywall? Let me know what would be the best way to do this or any ways I could improve. Thank you!!! submitted by /u/jyto3 [link] [comments]
