Complimentary crossovers that reduce phase distortion in loudspeaker systems, typically pairs, are described. In the fundamental embodiment, each loudspeaker possesses two drivers, a woofer and a tweeter. The “effective third-order” crossover on the right-hand loudspeaker remains “symmetric,” but the “effective third-order” crossover on the left-hand loudspeaker is rendered “asymmetric,” as described. Other embodiments apply this principle to higher crossover orders and greater numbers of drivers. This technology can be combined with other circuits like a Zobel, typically used for impedance correction. Some configurations of “phase-unified” loudspeakers require that a Zobel is applied to all drivers except the tweeter. Accordingly a rule combining effective crossover order and handedness is established. |
