I'd like to get some advice on installing a pair of 80F/X-RT in-ceiling speakers. As you may know, these speakers have an off-center speaker cone that allows the speakers to be aimed.

These speakers occupy a place about a foot and a haf from a wall on each side of the room. My question is 'should I aim the speakers cone toward the wall to diffuse the sound, or aim them toward the center of the room' and away from the walls?

All assistance appreciated,
