I am in the process of framing 8" x 24" soffits in my basement media room. I will be installing recessed lights in the soffits and attaching crown molding on them through which I will route rope lighting. The soffits will be around both sides and the rear of the room, with a 32" split in the rear soffit for placement of the projector. They are 2x2 and 2x4 construction because I was originally going to sheetrock them. Attached pictures show the sides of the room. (I still need to attach the soffit that will be over the door.)
After reading a lot on this forum, however, I'm wondering if it would be better if I covered the soffits with fabric and stuffed them with insulation around the IC recessed lights to create a bass trap(s).
So here are my questions:
Should I make all three soffits into base traps? Only the rear wall? Only the side walls?
Should I leave both the vertical face and bottom of the soffit "open" and covered with fabric? Just the bottom? Just the vertical face? How will the rope light look if the vertical face of the soffit is fabric?
If its best to leave both bottom and vertical side open, I am thinking about installing a 14" wide strip of MDF along the bottom/inside edge of the soffit on which I can mount my lights. It will extend inside the vertical face of the soffit about 2-3" to serve as a tray for the rope light and HDMI to the projector. (I've attached a rough sketch of what I'm thinking.) That should leave at least 14" of open space between the wall and the MDF along the bottom of the soffit. Will that work for a bass trap?
Thanks in advance for any suggestions.
