DD Audio HI-DEF SL612

Description

The SL600 series subwoofers, which include the DD Audio HI-DEF SL612 12" (30cm) flat subwoofer, are characterized by a very shallow installation depth and the suspensions have been tuned to perform excellently in closed and small bass reflex enclosures. To ensure high power handling, good cooling and high excursion, the SL600 subwoofers are equipped with 2.5-inch high-temperature voice coils, 72-ounce magnets, back wall coil venting and an EROM surround. One of the unique features of the SL600 is the three-layer flat cone. By compressing a layer of foam between two layers of cellulose, the cone is as light and stiff as a standard cone, yet flat enough to provide a suspension travel equivalent to that of a full-size subwoofer.
