Abstract:
Example techniques involve balancing bass response of a multiple driver playback device. An example playback device receives left and right channels of audio content and generates a center channel of the audio content by combining at least a portion of the left right channels. The playback device generates first and second side channels of the audio content by combining the center channel and a difference of the left channel and the right channel and combining the center channel and an inverse of the difference of the left channel and the right channel, respectively. The first and second side channels are attenuated by a filter with a given cutoff frequency. The center channel is amplified in proportion to the attenuation of the first side channel. The playback device plays back the first side channel, second side channel, and center channel according to respective radiation patterns having maximums aligned in respective directions.

Claim (Index 17):
A tangible, non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause a playback device to perform a method comprising:\n receiving, at the playback device, left and right channels of audio content; generating a center channel of the audio content, wherein generating the center channel comprises combining at least a portion of the left channel and at least a portion of the right channel; generating first and second side channels of the audio content,\n wherein generating the first side channel comprises combining (i) the center channel and (ii) a difference of the left channel and the right channel, and \n wherein generating the second side channel comprises combining (i) the center channel and (ii) an inverse of the difference of the left channel and the right channel; \n playing back the audio content, wherein playing back the audio content comprises:\n applying one or more filters to attenuate portions of the first side channel below a cutoff frequency; \n playing back the first side channel according to a first radiation pattern having a maximum aligned with a first direction; \n playing back the second side channel according to a second radiation pattern having a maximum aligned with a second direction; \n amplifying the center channel in proportion to the attenuation of the first side channel; and \n playing back the center channel of the audio content according to a third radiation pattern having a maximum aligned with a third direction.
