Re: How much does orientation of sub cabinets matter?
If you end up placing them under the stage-BE SURE to build a proper enclosure to put them in!!! Or you will be fighting a whole new set of problems.
Make enclosure just a little bit larger than the actual cabinet (allowing enough room to slide them in and get them out if needed-NOT and extra foot or two.
It is a good idea to plan on and stuff a little bit of foam (open cell is best to keep the vibration from being trasfered to the walls) around the sides and back to keep the cabinet from moving and touching the walls.
Be sure to use DOUBLE layer 5/8" sheet rock and glue and screw them together-no nails. Caulk with acoustical caulk (drywall mud can crack) ALL seams on each layer of sheetrock. Make sure the cormers are done oposite how the meet to help avoid leakage. ie on layer 1 walls go to the very top. Then the edge of the top butts into the wall. On layer 2 the top goes all the way to the side and the walls butt into the top.
Be sure to caulk the cable entrance into the cavity.
