The drivers are arranged in a three-way frequency crossover for smooth performance with lower distortion in the output signal. The DD driver delivers a powerful, deep-hitting bass response which gets complemented by a custom Knowles ED for the midrange and two Knowles RAD drivers for the high-frequency band.
