Abstract: A reconfigurable speaker system for producing sound in response to at least one of right and left channel audio signals generated by an audio source. The speaker system can be configured by the user to simultaneously reproduce right and left channel audio information from a single speaker, or the speaker system can be configured to reproduce right and left channel audio information independently from a pair of speakers. The speaker system includes a dual voice coil woofer and a pair of independent tweeters. A switch device is provided in circuit with the woofer and pair of tweeters so that in one position of the switch device, the dual voice coil woofer is configured to produce sound in response to both of the right and left channel audio signals, and each tweeter in the tweeter pair is configured to produce sound in response to a respective one of the right and left channel audio signals.

Abstract: A sound and light apparatus including a lamp and a speaker. The sound and light apparatus can be used indoors or outdoors to enhance a landscape plan or an interior design plan. Multiple sound and light apparatuses can be used to further enhance the ambiance of the indoors or outdoors location.

Abstract: Some embodiments of the present invention employ a subwoofer speaker adapted to be recessed within a wall or other building structure. In another aspect of the present invention, an amplifier is adapted to be recessed within a wall or other building structure, and can be employed with the recessed subwoofer or with another component of an entertainment system. In some embodiments, the subwoofer speaker is mounted in a wall cavity and supported therein with brackets. If desired, the amplifier can be supported by a frame within a wall cavity.

Abstract: A powered or active sub-woofer speaker system includes a power supply circuit, an audio amplifier circuit and a sub-woofer audio driver. The power supply circuit includes a toroidal power transformer to supply power to the audio amplifier circuit. The amplifier circuit includes a class-D audio amplifier adapted to amplify signals received from an audio source and to couple them to the sub-woofer audio driver. Each of the power supply circuit, audio amplifier circuit and sub-woofer audio driver has a low profile to permit the sub-woofer speaker system to be mounted in a closely confined space such as a house wall cavity.
