The base portion first side is disposed adjacent the convex surface of the diaphragm and defines a compression chamber therebetween. The base portion includes a plurality of channels that extend therethrough from the first side to the second side for sound waves to travel through the base portion, the plurality of channels converging to form an annular exit of the compression driver.
