Patent ID: 8259962

Claim:
An audio system comprising: at least one first speaker configured to emit an audio output; at least one second speaker configured to emit an audio output; at least one low-frequency output speaker configured to emit an audio output; and a receiver in electrical communication with said at least one first speaker and said at least one second speaker and said at least one low-frequency output speaker, said receiver being configured to alter a signal communicated to said at least one first speaker and said at least one second speaker and said at least one low-frequency output speaker such that said audio outputs thereof are inversely proportionally faded between the first speaker and one of the second speaker and the low-frequency output speaker, and said receiver includes, a filter in electrical communication with said at least one first speaker, said filter including a cutoff frequency, and a processor in electrical communication with said filter and configured to alter the cutoff frequency of said filter, wherein when said fade occurs so as to decrease at least one of said audio output of said second speaker and said audio output of said low-frequency output speaker the audio output of said first speaker increases as the processor decreases said cutoff frequency of said filter in response to said fade so that a low frequency output of said signal associated with said decreased cutoff frequency is further electrically communicated to ensure said increase in said audio output of said first speaker, and wherein said receiver further includes, a high pass filter in direct electrical communication with said second speaker, and a low pass filter in direct electrical communication with said low-frequency output speaker, and wherein the filter that is in electrical communication with said at least one speaker is a high pass filter and said receiver further includes, a front fader gain device receiving an electrical output from the processor and being an electrical input to the high pass filter in electrical communication with the first speaker and configured to receive an audio input signal disposed in the receiver, a rear fader gain device receiving an electrical output from the processor and being an electrical input to the high pass filter in electrical communication with the second speaker and an electrical input to the low pass filter in electrical communication with said low-frequency output speaker, and an output level sensor having an electrical output received by the processor and respective electrical inputs received from an electrical output of the high pass filter in electrical communication with the first speaker and an electrical output of the high pass filter in electrical communication with the second speaker.
