ABSTRACT:
An acoustic system is described for accurately reproducing sound. The acoustic system generally includes driver which produces a plurality of higher frequency pressure waves at larger amplitudes and produces lower frequency pressure waves at smaller amplitudes. A passage is provided which serves as an amplifier and resonator for the lower frequency pressure waves. Accordingly, the system accurately reproduces a large range of higher and lower frequency sounds.
