One Bazooka EL Bass Tube for Sale. Nice sounding passive subwoofer in a tidy compact design. Used, but in good working condition. Below is info from the manufacture... Add strong bass to your system with space-saving Bazooka Bass Tubes. Hook up one or more passive EL series tubes to an amplifier with a low-pass crossover, mount your tubes in a corner of your trunk, behind a rear seat, or in the back of your SUV, and experience a new dimension in music. The EL tube features a 6.5-inch long-throw woofer, and it's extra efficient, too, so you can mate one with a relatively small 2-channel amp in its bridged mode and still get lots of punch. Bazooka tubes fit in many locations that can't accommodate large, box-loaded woofers, so you'll have plenty of remaining cargo room. The driver has a twin layer compressed foam surround for smooth woofer excursion and four-layer voice coils for high power handling. * Efficient ported enclosure designed for corner mounting in your trunk, hatch or behind the seat of your pickup truck * Spring-clip wire terminals * Impedance: 4-ohm * Fequency response: 39 ~ 1,500 Hz * Handles: 100 watts RMS * Sensitivity: 100 dB * 10" x 8.25" x 18" long
