The S5 is a high-performance, all-in-one wireless music system that delivers crystal-clear, room-filling sound. Simply plug it in wherever you want music and enjoy. The 5-driver speaker system is individually powered by 5 dedicated digital amplifiers and includes 2 tweeters, 2 mid-range drivers and 1 subwoofer for high-quality sound that rivals much larger, more complicated audio equipment. To start playing music, one ZonePlayer or ZoneBridge must be connected to the router, then all the rest work wirelessly. The S5 is available in both black and white.
