A compact and portable loudspeaker system operable in two configurations includes a driver array and a base unit having a bass enclosure and a dock. In an extended configuration, the driver array is supported by one or more extension legs between three to eight feet above the base unit where one of the extension legs is held by the dock. The base unit may be placed on a floor of a small to medium venue with the mid-to-high range driver array elevated near or above the elevation of an audience in the venue. In a compact configuration, the driver array is directly supported by the dock and the base unit and driver array may be placed on a table or desk in a classroom, conference room, or other such small to medium venue. The portable loudspeaker system may be transported in the compact configuration.

Dual configuration speaker

A loudspeaker enclosure is formed with fins that may be extended to support the enclosure on a surface and retracted into mating recesses to comprise a cosmetically appealing outer surface when the enclosure is suspended.
