A free standing frame supports front, back, side, top and bottom panels in such a manner that the panels are free to move relative to each other. Speaker drivers are mounted to the front panel such that frontwave radiation therefrom is allowed to project outwardly. Rear wave radiation is, however, contained within the enclosure formed by the panels. Deflection of the panels as a result of impinging backwave energy dissipates the backwave without producing "ringing" or other resonant effects.
