The Acoustic Wave Music System II was judged to be expensive and lacking in performance and features compared to its competitors. In 2006, Bose introduced the new Acoustic Wave Music System II, which added MP3 CD playback, a Boselink port and a headphone output. In 1992 that Bose replaced the cassette player with a CD player (the CD2000), but Bose continued to sell a cassette player version (the CS2010) as an alternative to the CD version until the Acoustic Wave Music System v3 (CD3000) replaced both of them in 1996. It uses two 2 inch tweeters, and a four inch woofer (which is the only speaker utilizing the Wave Guide), a cassette player, and an AM/ FM radio into a mid-sized tabletop stereo system. In 1984 the original Bose Wave system, called the Acoustic Wave Music System (AW-1), was Bose's first-ever tabletop radio.
