Bazooka Bass Tube enclosure is optimised for corner loading. The Bass Tubes enclosure's port and woofer are on the same plane and in close port for maximum corner loading results. And, a megaphone amplifies a cheerleader's voice, the corner of your car amplifies the concentrated bass output of the Bass Tubes enclosure. The Bass Tubes enclosure's advantage is it fits any vehicle. It's perfect fit for a perfect sound.
