Cool light box sound system. Perfect for kitchen or bedroom dance parties. The middle box is actually a little subwoofer so the sound is pretty decent for a fun system like this. This is NOT a Bluetooth system. You plug it into the wall and your sound source plugs in with a 1/8" stereo cable (included). The middle (large box) subwoofer is 8 inches high, just to give you an idea of how big it is. It doesn't take up a lot of space.
