Boombox is a common term for a portable
cassette and AM/FM radio (and, beginning in the 1990s, a
CD player) with an amplifier, two or more
loudspeakers and a carrying handle. A boombox is a device typically capable of receiving
radio stations and playing recorded
music (usually
cassettes or
CDs, usually at a high
volume). Many models are also capable of
recording onto cassette tapes from radio and other sources. Designed for portability, boomboxes can be powered by
batteries as well as by line current. The boombox was introduced to the American market during the mid-1970s. The desire for louder and heavier bass led to bigger and heavier boxes; by the 1980s, some boomboxes had reached the size of a
suitcase. Most boomboxes were battery-operated, leading to extremely heavy, bulky boxes.
