    Abstract: Disclosed is a swivel speaker system to custom-aim sound emanating from the speaker towards a listener. A speaker device of the present system comprises a sound driver disposed within a mount positioned within a housing. The mount swivels within the housing to direct the radiating frequencies to a desired location within a unique environment without obstructively projecting from a mounting surface.

Additionally, the speaker system, in accordance with another embodiment, provides a modular system having interchangeable support components which customizes the speaker to adapted to unique mounting surfaces in unique listening environments.
