JVC, or the Japan Victor Company launched themselves into the portable radio cassette player/recorder market in the late 1970’s when they released the amazing RC-550(Image 2). Dubbed “El Diablo” by the Latino community, this giant monobox was devilish. It had a 10” woofer, a 4” midrange, and a 2 “ tweeter, separate bass and treble controls, and a big strong handle as well as a shoulder strap. It had roll bars on the sides that extended forward to protect the speakers and even had shortwave bands as well. This unit was built for the streets, and signaled a change in the mindset of portable design, although not a stereo player, this unit was BIG!
