The SL600 Series subwoofers give you the bass you want, in almost any space you want to put it. They feature super shallow mounting depths, and the suspensions have been tuned to perform in sealed and small vented enclosures. 

To maintain power handling, cooling and excursion the SL600s utilize full size sub features such as 2.5″ high temperature voice coil, 72oz magnet, back plate coil gap venting, and an EROM surround.

One of the features unique to the SL600s is the triple layer shallow body cone. By compressing a layer of foam between two layers of pulp the cone is kept as light and rigid as a standard cone, yet shallow enough to allow suspension travel equal to a full size sub.
