Claim 0:
1. A speaker system comprising:
a plurality of pairs of sealed speaker cabinets;
first and second speaker drivers mounted to each of the pairs of sealed speaker cabinets, wherein each sealed speaker cabinet houses a driver, wherein each driver faces outward from the sealed speaker cabinet in which it is mounted, wherein each driver is a low-frequency driver for reproducing bass frequencies in a range including 200 Hz; and
an audio processing apparatus configured to receive a first audio signal and to process the first audio signal to generate a second audio signal, wherein the first audio signal is delivered to the first and second speaker drivers in at least one of the pairs of sealed speaker cabinets, and the second audio signal is delivered to the first and second speaker drivers in at least one other of the pairs of sealed speaker cabinets, wherein the first audio signal is configured to operate the first and second speaker drivers in the at least one of the pairs of sealed speaker cabinets below a fundamental resonance frequency of the first and second speaker drivers as mounted in the at least one of the pairs of sealed speaker cabinets, and the second audio signal is configured to operate the first and second speaker drivers in the at least one other of the pairs of sealed speaker cabinets below a fundamental resonance frequency of the first and second speaker drivers as mounted in the at least one other of the pairs of sealed speaker cabinets,
wherein each sealed speaker cabinet in each pair of sealed speaker cabinets is rigidly secured, either directly or indirectly, to the other sealed speaker cabinet in that pair of sealed speaker cabinets and the first and second speaker drivers are oriented in a manner to minimize vibration producted by forces transmitted from the first and second speaker drivers to the respective pair of sealed speaker cabinets.
