Claim 16:
17. A speaker system comprising:
a pair of sealed speaker cabinets, including a first sealed speaker cabinet rigidly secured to a second sealed speaker cabinet;
a first speaker driver mounted in the first sealed speaker cabinet, wherein the first speaker driver has a first side that emits primary sound radiation and a second side opposite the first side, and wherein the first side of the first speaker driver faces outward from the first sealed speaker cabinet, wherein the first speaker driver is a low-frequency driver for reproducing bass frequencies in a range including 200 Hz;
a second speaker driver mounted to the second sealed speaker cabinet, wherein the second speaker driver has a first side that emits primary sound radiation and a second side opposite the first side, and wherein the first side of the second speaker driver faces toward an inside of the second sealed speaker cabinet, wherein the second speaker driver is a low-frequency driver for reproducing bass frequencies in a range including 200 Hz; and
an audio processing apparatus in signal communication with the first and second speaker drivers and configured to receive a first audio signal and to process the first audio signal to generate a second audio signal, wherein the second audio signal is delivered to the first and second speaker drivers, wherein the second audio signal is configured to operate the first and second speaker drivers below a fundamental resonance frequency of the first and second speaker drivers as moounted in the pair of sealed speaker cabinets,
wherein the first and second speaker drivers and the pair of sealed speaker cabinets are oriented in a manner to minimize vibration produced by forces transmitted from the first and second speaker drivers to the pair of sealed speaker cabinets.
