Claim 0:
1. An audio system for enhanced listener localization of played-back sound comprising:
an audio source adapted to play back an audio recording having left and right audio recorded channels;
a right main loudspeaker connected to the audio source and adapted to transduce sound corresponding to the right audio recorded channel;
a left main loudspeaker connected to the audio source and adapted to transduce sound corresponding to the left audio recorded channel;
a right side localization loudspeaker connected to the audio source and adapted to transduce sound corresponding to the left audio recorded channel after the left audio recorded channel is passed through a first low-pass filter; and
a left side localization loudspeaker connected to the audio source and adapted to transduce sound corresponding to the right audio recorded channel after the right audio recorded channel is passed through a second low-pass filter,
wherein the first low-pass filter and the second low-pass filter each comprise a filter having a cutoff frequency of between approximately 2.0 kHz and approximately 2.5 kHz and decrease power above the cutoff frequency at approximately 6 dB per octave.
