ABSTRACT:
An audio surround-sound system includes a main enclosure, an audio decoder device to decode audio source signals supplied by an audio source device to provide decoded audio signals, and at least a first and second low distortion amplifier housed within the main enclosure to receive and amplify the decoded audio signals. Also included is at least a first and a second speaker element operatively coupled to the at least first and second amplifiers, respectively, to produce the audible signals, where the audible signals are received by the listener from a first and second direction. A local radio transmitter converts a portion of the decoded audio signals into radio modulated signals and transmits the radio modulated signals where a wireless receiver receives and converts the radio modulated signals into remote audio source signals. A third speaker element produces audible signals to be received by the listener from a third direction, where the third speaker element is operatively coupled to a third low distortion amplifier. The third low distortion amplifier receives and amplifies the remote audio source signals, where the third low distortion amplifier, the wireless receiver and the third speaker element are remotely located from the main enclosure. The audible signals received by the listener from the first, second, and third directions operatively surround the listener with the audible signals.
