After wiring my basement theater (15x23) for 7.1 I started thinking about hiding the 4 satellites in the floor joists so they would be flush with the drywall leaving only speaker grill exposed. Clearly this means they will be facing down rather than angled toward the seating, is this a problem? Because it's a basement the ceilings are not very high and despite the rectangle size of the room the actual seating/veiwing area will be almost square. If I give careful consideration to speaker placement, will I still get quality sound with them mounted this way? Or should I stick to low-budget convention for the best sound and wall mount them?
