Abstract
The speaker system disclosed includes multiple closely spaced drivers in a column matrix format. Using signal processing and pairing of the drivers, the speaker system optimally combines acoustic output and maintains the benefits of a single column vertical array while achieving improved low frequency sound production by coupling speakers through spatial and frequency alignment. The full frequency range of an audio signal is provided to a first set of drivers while a low frequency band of the audio signal is provided to a second set of drivers. The horizontal centers of the two adjacent sets of drivers are such that the signal wavelength provided to the second set of drivers is at least twice the separation distance between transducer acoustic centers. By providing a continuous range of signal to at least one driver set, and proper frequency management of the second set, crossover artifacts are substantially minimized while the benefits of coupled drivers are optimized.
