We're starting a basement development project and I've been "green lighted" by SWMBO for a proper listening room. Problem is, the layout may be compromised due to the desire to not feel like you're walking down into a hallway. Have a look at the picture for what is in the plans. The room is going to be about 12x17' and will have a corner notched off to permit the aesthetic mentioned above. In order to have symmetry, I think a component rack/closet of a matching shape would balance it out. Access door to the adjacent room for cable management I'm fortunate to have a 105" rough height to deal with. Looking to use mineral wool in the joist spaces above and on the sides. Drywall attached using resilient channel. The doors would be exterior grade french doors with gaskets and sweep threshold to keep sound contained . Treatments would follow after construction is complete. Thoughts? Ideas?
