1. A playback device comprising:

  • a network interface;

    a processor;

    a plurality of speaker drivers;

    at least one orientation sensor; and

    tangible, non-transitory computer-readable memory including instructions stored therein, wherein the instructions, when executed by the processor, cause the playback device to perform functions comprising;

    receiving an audio data stream via the network interface;

    determining, via the at least one orientation sensor, a change in orientation of the playback device from a first orientation to a second orientation, wherein the determining includes (i) detecting for a change in pitch relative to a pitch axis of the playback device and (ii) detecting for a change in roll relative to a roll axis of the playback device, wherein the roll axis is perpendicular to the pitch axis;

    routing a first set of frequencies in the audio data stream to at least one of the plurality of speaker drivers when the playback device is in the first orientation; and

    routing a second set of frequencies in the audio data stream to the at least one of the plurality of speaker drivers when the playback device is determined to be in the second orientation, wherein the first set of frequencies is different than the second set of frequencies.
