Retractable speakers for use in a housing coupled to a computer, such as a portable computer or docking bar, which allow for sound quality optimization by being positionally adjustable relative to the computer housing. Retractable speaker locations relative to the computer housing include the top surface, side surfaces or front surface. Speakers are rotatable about a hinge relative to the housing surface, or emerge from the surface, such that the speaker is rotatable about an axis in order to direct the sound output toward a user. Alternatively, speakers disengage from the computer housing for placement on a surface in an optimum sound quality arrangement. Retracted speakers are substantially internal to the computer housing allowing for ease of transport and use in remote locations.
