Systems, methods, and apparatus to filter audio are disclosed. An example method includes determining that an orientation of a playback device is one of (a) a first orientation and (b) a second orientation, the playback device including a first speaker and a second speaker and configuring the first speaker and the second speaker. In the example, configuring the first and second speakers includes, when the determined orientation is the first orientation, configuring a first audio filter to be applied to a first audio signal for the first speaker and configuring a second audio filter to be applied to a second audio signal for the second speaker. However, when the determined orientation is the second orientation, configuring the first and second speakers includes configuring a third audio filter to be applied to the first audio signal and the second audio signal. |

1. A method comprising:
determining, by a playback device, that a physical orientation of a playback device is one of (a) a first physical orientation and (b) a second physical orientation, the playback device including a first speaker and a second speaker; configuring, by the playback device, the first speaker and the second speaker, wherein configuring the first and second speakers comprises: when the determined physical orientation is the first physical orientation, configuring, by the playback device, a first audio filter to be applied to a first audio signal for the first speaker and configuring a second audio filter to be applied to a second audio signal for the second speaker, wherein the first audio filter and the second audio filter cause a first frequency response of the first speaker to dominate a second frequency response of the second speaker in a frequency range, wherein a third speaker is in between the first speaker and the second speaker, and wherein the frequency range is based on a distance between the first speaker and the second speaker; and, when the determined physical orientation is the second physical orientation, configuring, by the playback device, a third audio filter to be applied to the first audio signal and the second audio signal; and facilitating playback of audio via the playback device according to the filtered first audio signal and the filtered second audio signal. |
