The flat-panel speakers of this audio system have advanced NXT SurfaceSound, a patented speaker design technology which generates a rich, unmuddied sound despite a compact, ultra-thin speaker. The sleek, powerful stereo system uses 65 total watts of power to fill any size room with music or home theater audio, boosted by ample bass from the included subwoofer. The system plays a variety of CD formats (CD, CDR, CDRW, and MP3-CD) in addition to its 20 AM/FM presets. Includes both auxiliary In and Out jacks to link up additional audio sources, such as an iPod or additional speaker sets. The system also features a 3-band equalizer with 7 preset EQ audio effects for fine-tuning sound. Compact enough for small spaces; the slim speakers are wall-mountable, or the system can rest on a shelf, tabletop, or counter. 12" H x 17 1/2" W x 24" L. (20 1/2 lbs.)
