The "Wave Radio" (which has since become known as "Wave Radio I") was an AM/FM clock radio that was introduced in 1993. It was smaller than the Acoustic Wave Music System and used two 2.5-inch speakers. A "Wave Radio/CD" model was introduced in 1998 and was essentially a Wave Radio I with a CD player. The end of the waveguides were tapered by 2%. Unlike the Acoustic Wave, the Wave Radio could be used as an alarm clock radio, and featured two independent alarms, which could be set to A/M or F/M radio, a buzzer, or a device plugged into the auxiliary input.
