Abstract
An omni-directional acoustic deflector includes an acoustically reflective body having a truncated conical shape including a substantially conical outer surface, a top surface and a cone axis, the acoustically reflective body having an opening in the top surface centered on the cone axis. An acoustic absorber is disposed at the opening in the top surface. The deflector may also include at least one opening disposed along a circumference of the substantially conical outer surface at a cone radius associated with a pressure maximum of an acoustic resonance mode with an acoustic absorber at each such opening. Speaker systems employing the omni-directional acoustic deflector have an improved high frequency acoustic spectrum response regardless of the location of the listener with respect to the speaker system.
