Abstract:
A speaker system for reproducing a stereophonic audio signal generated by an audio signal source having a left channel signal L and a right channel signal R, comprising:first left channel filter means for filtering the left channel signal L to substantially eliminate acoustic frequencies below a predetermined threshold;second left channel filter means for filtering a left difference signal to substantially eliminate low and midrange acoustic frequencies, the left difference signal defined as a difference between the left channel signal L and the right channel signal R;a left satellite speaker for providing an acoustic output, the left satellite speaker having a first and second audio output source, where the first audio output source provides an acoustic output in response to the filtered left channel signal, and the second audio output source provides an acoustic output in response to the left filtered difference signal;first right channel filter means for filtering the right channel signal R to substantially eliminate acoustic frequencies below a predetermined threshold; andsecond right channel filter means for filtering a right difference signal to substantially eliminate low and midrange acoustic frequencies, the right difference signal defined as a difference between the right channel signal R and the left channel signal L; anda right satellite speaker for providing an acoustic output, the right satellite speaker having a first and second audio output source, where the first audio output source provides an acoustic output in response to the filtered right channel signal, and the second audio output source provides an acoustic output in response to the right filtered difference signal.
