The Rockville Punisher 8D2 is an 8-inch dual 2-ohm car subwoofer built for high-power competition use. It carries a 145 oz double-stacked Y35 magnet, a cast aluminum basket and a 2.5-inch four-layer aluminum voice coil wound with OFC wire. Rockville rates it at 750 watts RMS and 3,000 watts peak, and the heavy motor and thick cone are aimed at buyers pushing big power in small enclosures. Against mainstream 8-inch subs it is far heavier and more overbuilt, but it needs a strong amp and a proper box to perform.

The Rockville Punisher 8D2 is an 8-inch dual 2-ohm car subwoofer built to handle heat and heavy use, including competition test tones. It weighs 24.26 lbs and has a 145 oz (9.06 lb) double-stacked Y35 magnet.
For cooling, it has an oversized aluminum heatsink ring near the T-yoke and an extra-thick 15 mm T-yoke with 12 mm washers, which absorb and dissipate heat. The T-yoke is vented. The 2.5-inch 4-layer black aluminum voice coils are wound with OFC wire and are stable up to 250 degrees Celsius. The windings are made in the USA, and high-temperature black glue is used in the build.
The cone is black, non-pressed paper with black stitching, and it has a thick foam surround. The dustcap is polypropylene and 0.9 mm thick. The cast aluminum basket has a black sanded finish. A custom Rockville mounting gasket is included for mounting, and recone kits are available. A vented enclosure is recommended for this model.
