JVC Kaboom! Series RV-B550

JVC Kaboom! Series RV-B550 ... Channel, Two-Step Active Hyper Bass PRO and Active Clear Sound. A 4-Layer Voice Coil shifts down the lowest resonance frequency and increases driving power. Long Labyrinth Ducts extend the frequency response down to the lowest frequencies. Synchronized CD/Cassette Dubbing starts compact disc playback when cassette recording begins. Full logic cassette controls allow you to go directly from Fast-Forward to Rewind without first pushing play. The RV-B550 is available in either a translucent red or blue color with matching speaker illumination - the illuminated center cap blinks with the rhythm of the music.
