The JVC Kaboom is back! The new RV-NB70 Kaboom boasts 40 watts of power and retains the original's general design - a large cylindrical shape with a woofer at each end. Bass enhancement circuitry ensures room-rattling low frequency performance. Digital era upgrades include a dock for iPod and iPhone, which is shielded from the elements by a protective door, and USB Host for playback of music files stored on a USB mass storage device. We have strengthened this years model by adding a guitar and microphone input with mixing capabilities making this truely a full featured device. In addition, there's a CD player that can handle MP3 and WMA file playback, and an FM tuner. A remote control makes it easy to operate while a shoulder strap makes it a cinch to carry.
