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 11):
The playback device of  claim 9 , wherein the method further comprises applying the one or more filters to attenuate portions of the second side channel less than the cutoff frequency, and wherein amplifying the center channel in proportion to the attenuation of the first side channel comprises amplifying the center channel in proportion to the attenuation of the first side channel and the second side channel.
