    Home Audio Acoustics
    I'm in the process of adding acoustic treatments to my 20'x15' home theater. At this point I've added a false wall 2' from the original wall, installed a super chunk bass trap in the front right corner and added a 6" layer of mineral wool over the entire front wall. I'm in the process of...
  2. Soffit question

    Home Audio Acoustics
    I'm planning on building some 8" tall x 12" wide soffits in my small theater room (11' x 15'). Would that size of soffit be good enough to use as bass traps? Thought about building the frames and covering them in fabric so that the sides and bottom would be open. I have some Roxul AFB that I...

  4. Help securing soffit

    Home Theater Design and Construction
    Hi all. I'm in the process of building my soffits surrounding a couple of steel beams supporting the main floor above. My plan is to use 2 layers of 5/8" DW with GG in between, and secure the soffit to the hat channel on either side of the steel beam by way of a 2x2 screwed through one layer...

    Home Audio Acoustics
    OK, I have an acoustical in nature question. I am going to be starting on false soffits this weekend and I am thinking about using 2x2's for the framework and then covering the top (which would affix to the ceiling) and the bottom (which is the side where the lights will be mounted) with...

  7. Speakers behind stud wall, soffit construction

    I'm preparing to strip the drywall and plywood from a shear wall at the front (17') of my room (16' long x 17' wide x 9' high).

  9. Effect of soffit in a HT

    Home Audio Acoustics
    Hi guys, I'm in the process (slow) of building a HT and am trying to plan the soffits. I'm tossing up whether to frame the soffits and then cover them with gyprock/sheetrock OR frame them and cover them with fabric. Do you guys think it will affect the acoustics with the more solid...

    I've been putting off :rolleyes: treating some odd dimension wall/corner areas behind my listening area and my choices are wedges 12" by 24" (along the straight edges) or a soffit 10" high by 12" wide. I'm leaning toward the soffit and was wondering if anyone had thoughts on how build one...
