Abstract
A subwoofer is equipped with a wireless receiver to receive signals containing information for a Low Frequency Effects (LFE) channel and information for both surround channels. In one form, the LFE is added to one or both surround channels to provide a stereo surround signal (containing both surround channels) including a multiplexed LFE channel. The subwoofer utilizes the LFE channel, powers surround speakers, and passes the surround signals to respective surround speakers. A receiver multiplexes LFE signals into either one or both surround sound audio channels. A digital RF transmitter of the receiver transmits the combined subwoofer/surround channels to the wireless receiver of the subwoofer. The remote subwoofer is connected to a power source. The surround speakers are connected to the subwoofer so as to receive the surround channels and be powered thereby.
