For some reason I'm loosing high frequency detail in my family room and fighting very slightly excessive sub-bass (Serenity's opening scene almost shakes pictures off the walls). Bass and mid-bass are fine but the lack of H-F detail is making me crazy. I want to upgrade to high buck speakers (maybe Song Towers) but not until I fix the room. My existing speakers worked great in my old house so all I can figure out is maybe reflections are canceling out the H-F details.
Anyway I'm looking at adding some treatments to my family room and wanted to run my plan by others. I conferred with
ATS and this was what we worked out. BTW, the family room and hall have very deep carpet. Opinions?
I'll fill in some details to the drawing. The total space is 20' from the back wall to the entertainment-center's wall and 24' from the sliding glass door to the back wall of the kitchen. The kitchen cabinets are oak and there is no cottage cheese on the textured ceiling. The (speaker spot) distance from the TV to the side wall and the cabinets is 20" and the TV is a 52" LCD 18" from the back wall. The angled area is a fireplace. Yes it's all a tight fit.
I've discussed this with ATS and this is my plan so far. Two corner mounted backless 24" (W) x 48" (H) x 4" (T) bass traps at 45 degrees in the lower rear corners. Four 24x48x2" panels mounted above the couch along the back wall, plus two 24x24 mounted as decorative diamonds between/on top of the 24x48 panels, and two 22x48x2 panels on the rear side walls mounted even with the back panels. 8 feet of panels will (with spaces) cover 3/4 of the width-area of the back wall and will extend from 4' to 8' up the 12 foot tall back wall.
My fall back if this doesn't do enough is six 24x24x2" panels above the 24x48x2" panels.
