Abstract
A playback device identifies a first audio filter and a second audio filter. The first audio filter is configured to have a first frequency response and the second audio filter is configured to have a second frequency response. The audio input is processed according to the first audio filter and the second audio filter to produce respective first audio output and second audio output. The first audio speaker renders the first audio output and the second audio speaker renders the second audio output, where the second frequency response of the second audio filter compensates for interference between the first audio output rendered by the first audio speaker and the second audio output rendered by the second audio speaker.
