A method of minimizing edge reflections of vibrational waves in a flat panel speaker assembly for a stereo device by characterizing the impulse response of the flat panel and associated components in response to a test signal to produce a cancellation signal, and applying the cancellation signal for each stereo channel to the opposing stereo channel.
