Sound Ordnance

Sound Ordnance designed the B-17 bandpass subwoofer to be the bass fortress in your vehicle's sound system. Its 12" polypropylene woofer is mounted inside a sturdy enclosure, between an airtight sealed chamber and a second chamber that boasts a generous slot port for massive air movement. This bandpass design increases speaker efficiency, for impressive bass firepower from a relatively small box. Best of all, you can watch the woofer swing into action behind the clear acrylic front window. 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. Need an amp for this sub? Check out this Crutchfield-approved bass package .
