OD SW21 is a High Velocity subwoofer that features an internally mounted 21" woofer driving (2) 6" Aerovents™. Located on the front panel, all bass emanates from these vents with air velocity reaching 1/10 the speed of sound! The resulting shockwave provides a more efficient acoustical impedance and transfer function that energizes the coverage area with much faster, extremely powerful and more efficient and deep bass.
