A low profile speaker enclosure for mounting on a structure including a speaker housing and an electroacoustical transducer is disclosed. The speaker housing has a front face and a back each defining a length and a width, and a plurality of sides substantially separating the front face and the back and defining a thickness of the speaker housing. In the preferred embodiment, the front face and the back are substantially parallel. The front face, the back, and the plurality of sides of the speaker housing substantially define a chamber. The front face defines a speaker aperture opening into the chamber. The electroacoustical transducer is mounted in the speaker aperture. At least one of the sides defines a side aperture. The back of the low profile speaker enclosure defines a channel and defines a back aperture providing an opening between the channel and the chamber. The side aperture is also defined by the channel. The structure at least partially encloses the channel and provides a pathway between the chamber and an exterior environment for increased acoustic performance.
