About the Sound Ordnance™ B-24
Sound Ordnance designed the B-24 dual bandpass subwoofer to be the bass fortress in your vehicle's sound system. The sturdy enclosure houses a pair of 12" polypropylene woofers in individual airtight sealed chambers, plus a third chamber that features a generous slot port for massive air movement. The enclosure's bandpass design increases speaker efficiency dramatically for impressive bass firepower. Best of all, you can watch the woofers swing into action behind the clear acrylic front windows.
The heavy-duty speaker terminals provide excellent connections, and the rugged black carpet cover with the Sound Ordnance logo lets your competition know you mean business. And you'll have extra peace of mind with Sound Ordnance's 3-year warranty behind your investment. Add a suitable amplifier, mount the system safely in your trunk or cargo area, and get ready for a bass barrage.

Materials: The Sound Ordnance B-24 is a pre-loaded bandpass-style enclosure with dual 12" subwoofers. It is constructed of ⅝" MDF (medium-density fiberboard), covered in black carpet. It also features dual clear acrylic front windows for viewing the subwoofers. The subwoofers feature polypropylene cones with rubber surrounds, 2" voice coils, and a heavy-gauge stamped steel basket.
Box Design: The enclosure has separate sealed chambers in front of each subwoofer, and a vented chamber behind both subwoofers. The front-firing slot port is 2-13/16" wide and 13-1/2" tall, and is centered between the speakers. The box has a total of 2.9 ft³ of airspace.
Terminals: The B-24 is equipped with a single set of spring-post speaker terminals, mounted in the rear panel. The terminals will accept bare wire, pin connectors, and single banana plugs, but are spaced too far apart for dual banana plugs. Inside the enclosure, the two 8Ω drivers are wired in parallel to present a 4Ω load at the speaker terminals.
Brackets: Brackets for securing the enclosure to your vehicle are recommended.
