This is a pre-loaded dual 8-inch subwoofer enclosure paired with Rockville's DB11 amplifier, sold as a matched bass package. The sealed-and-vented box uses 3/4-inch MDF, is tuned to 37 Hz, and holds two 8-inch woofers rated 400 watts RMS and 1,600 watts peak at a 2-ohm final impedance. The woofers use cast-iron baskets, 30 oz magnets, fiber-reinforced paper cones and 1.5-inch four-layer aluminum voice coils. It suits drivers who want a complete, pre-wired bass upgrade without matching components themselves. Against separate-component builds it saves setup work, but the 8-inch drivers and modest 0.80 cu ft per sub limit output compared with larger 10- or 12-inch setups.

This package pairs a loaded subwoofer enclosure holding two 8-inch subwoofers with a Rockville dB11 mono Class-D amplifier and a wiring kit. The enclosure is rated at 1600 watts peak and 400 watts RMS, with a final impedance of 2 ohms. The power ratings are CEA-2031 compliant.
The enclosure is built from 3/4-inch MDF that is bonded, stapled and braced. It has computer-designed vents angled at 15% and is covered in aviation-grade tweed carpet. Speaker wire connects through satin nickel push terminals. Each sub has 0.80 cu ft of air space, and the enclosure is tuned to 37 Hz.
Each subwoofer has a 1.5-inch 4-layer black aluminum voice coil wound with 100% copper (OFC) wire, a 30 oz magnet and a cast iron basket with a black sanded finish. The cone is non-pressed black paper reinforced with fiber. It has a thick foam surround, blue stitching cone reinforcement and a polypropylene dust cap. A vented hole in the T-yoke helps dissipate heat, and a Rockville-branded mounting gasket is included.
