Claim Text:
1. A speaker system, comprising: a resistance-controlled transducer, coupled to a unsymmetrical crossover network adapted to remove causal delay, said transducer comprising a diaphragm or cone with a voice coil, and a motor with a pole-piece with a conductive shorting ring, said shorting ring located in close proximity to and at the same height as the voice coil; and a mass-controlled transducer, coupled to the unsymmetrical crossover network adapted to remove causal delay, said transducer comprising a diaphragm or cone with a voice coil, and a motor with a pole-piece with a conductive shorting ring, said shorting ring located in close proximity to and at the same height as the voice coil; wherein electrical input impedance to the system is independent of frequency in both magnitude and phase; and further wherein the speaker system exhibits flat delay response.
