The Z-5500's subwoofer features a 10-inch speaker -- one of the largest on the market, according to Logitech. It sure does rumble, even at low volumes. At high volume, you can feel the wind.

The Z-5500's control console puts a big, illuminated volume dial right where you need it: front and center. It also has mini-jack inputs. Plug in an iPod's docking cradle, and you have a very loud iPod speaker system.
