A good subwoofer can make an average car audio system sound good, and a good car audio system sound great. Good bass is all about moving air, and a cylindrical tube translates the motion of its woofer into maximum air pressure so you hear and feel more bass. Bazooka designed the Bass Tube to act like a bass cannon, firing low frequencies throughout your vehicle. BT6014 6-1/2" Bass Tubes® enclosure The BT6014 Bass Tube features a 6-1/2" polypropylene woofer with a twin-layer compressed foam surround for smooth excursion. The 4-layer voice coil ensures reliable power handling for plenty of punch, and its 4-ohm impedance allows you to power multiple tubes with a single amp. The tube design eliminates standing bass waves for accurate response and high efficiency. Find a good spot for this Bazooka in your vehicle and you'll still enjoy plenty of cargo room. Bass Tubes enclosures fit just about anywhere A compact Bass Tubes enclosure will fit in almost any vehicle, and you can disconnect it in a snap if you need more cargo space. Since the tube's speaker and port are right next to each other, you can get amazing results by "corner loading" your tube — placing it in a corner of your trunk or cargo area so your vehicle's boundaries act as a natural amplifier, boosting bass production.
