Do high-mounted or ceiling-mounted bass traps, when they are located well above the tops of the loudspeakers, have to be symmetrical on both sides of the room?
Imagine seven foot tall speakers in a listening room with a 15 foot tall ceiling. A large, hollow, wood-framed soffit descends four feet from the ceiling on the left side of the room (starting at the ceiling and continuing down from the ceiling for four feet on the left side wall). This soffit is six inches deep in some areas and four feet deep in the front left corner of the ceiling. The entire soffit, at each depth, is filled with blue jeans insulation. The front left corner section is four feet tall (like the entire soffit) but is four feet deep and filled entirely with blue jeans insulation.
The entire soffit is open to the blue jeans insulation; the soffit is not covered with drywall or any other solid or reflective material.
What effect will this large, acoustically-porous, sound-absorbing, high-located area have on the acoustics of the room?
Will it absorb whatever bass frequencies hit the soffit, especially if they hit the four foot deep (and four foot tall) section in the upper left front corner?
Does it matter that there is no mirror image soffit on the right side of the room descending from the ceiling above the right side wall?
