Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Both woofers are visible behind the front clear plexiglas window. "JENSEN" is silk screened in black across the middle of the window, and a border around the edge of  the window is silk screened in black.

The panel to which the woofers are mounted is covered with gray box carpeting.
