The Rockville DV12K6D2 is a preloaded dual 12-inch subwoofer enclosure with two K6 series woofers already mounted and wired. It is aimed at car audio buyers who want a big bass upgrade without building a box or matching drivers themselves. The sealed dual-12 format is a common rival layout, but buying it loaded saves the box-building work that bare enclosures require. Owners of K6 woofers describe strong output for the money, while deep-bass extension and box finish are the usual trade-offs at this level.

Feedback on Rockville K6 subwoofers and DV-series enclosures centers on loud output for the money and easy setup. Owners note that the sealed box favors punch over very deep lows and that the enclosure is bulky.
The Rockville DV12K6D2 is a vented subwoofer enclosure loaded with two 12" Rockville W12K6D2 V2 subwoofers. The pair is rated at 4800 watts peak and 1200 watts RMS, and is pre-wired to a 2-ohm final impedance. The enclosure is tuned to 28 Hz.
The box is built from ¾" MDF with black carpet, and 1" MDF for the subwoofer mounting. It is bonded, stapled and braced, and has 10 gauge copper push terminals. The front panel is thick plexiglass with LED lighting that can be set to white or blue.
Each subwoofer has a 2.5" voice coil with a black aluminum former and 100% USA-made OFC copper wire. The motor uses double-stacked 100 oz magnets, and the basket is cast aluminum with a black sanded finish. The cone is fiber-reinforced, ultra-stiff, non-pressed black paper with a thick foam surround. Cooling comes from a vented T-yoke and a high BL magnetic motor gap.
