Tivoli Audio Music System Two Wireless Bluetooth Speaker (Black Ash/Silver) The Music System's separate amplifiers, custom drivers and adjustable bottomfiring subwoofer have all been retained in the Music System Two's design. Other engineering traits such as our popular SpacePhase wide mode, which produces an expansive soundstage, and the dual rear firing bass ports, which deliver extended bass response, are also incorporated. Additional features include AM/FM RDS, easytosee large display with backlight control, auto set digital clock with battery backup, fullfunction remote control, snooze and sleep timers, and dual, independent alarms. If you prefer to store data instead of CDs, then Tivoli Audio has you covered with the Music System Two.
