Title: DUAL ASYMMETRIC COMPRESSION DRIVER
Abstract:
In at least one embodiment, a dual asymmetric compression driver is provided. The dual asymmetric compression driver includes a first driver assembly and a second driver assembly. The first driver assembly is positioned about a central axis and includes a first annular diaphragm having a first planar section extending at a first clamping distance. The second driver assembly is positioned about the central axis and includes a second annular diaphragm having a second planar section extending at a second clamping distance. The first clamping distance is different from the second clamping distance causing the first asymmetric driver to provide a first audio output in a first frequency range and the second driver assembly to provide a second audio output in a second frequency range.
