This 60-watt bass-reflex audio system streams music wirelessly from an iPod®, cell phone, PDA, or any A2DP enabled Bluetooth stereo source up to 100' away. The built-in digital 2.1-channel Class-D amplifier controls two full-range drivers (80 Hz - 20) and a 4" sub-woofer independently to eliminate background noise and reduce distortion, delivering rich, vibrant sound, even at high volume. The speaker links to a Bluetooth streaming source at the press of a button and allows you to control its volume from afar through your device. It also can be connected to non-Bluetooth devices such as CD players and tuners via an RCA jack. The solid wood cabinet sports a semi-matte black laquered finish and includes adhesive feet to prevent scuffing. The 3/8" thick black fabric grille (not shown) has magnets for easy attachment and removal. Includes Bluetooth adaptor. Plugs into AC. 6" H x 17" W x 8 3/4" D. (12 1/2 lbs.)
