In DVD, D TV, and other A/V products, bass management is an important part of audio post processing. For some speaker configurations that lack a subwoofer, the combined low frequency components of the signals in the front and rear left channels, front and rear right channels, center channel, and LFE channel are sent to the two large speakers (see fig. 1). This may cause an overflow in the front channels and generate audible distortions, especially when the LFE signal is large.
