  • Our take on the W65K9D2

    The Rockville W65K9D2 is a 6.5-inch car subwoofer from Rockville's K9 line, built as a dual 2-ohm voice coil driver. The dual 2-ohm coils let you wire the sub to a 1-ohm or 4-ohm load, so it can match a range of amplifiers. It suits drivers who want a small-footprint sub for a sealed or ported box in a tight space, and Rockville's K9 subs are known as budget-oriented bass. Compared with name-brand 6.5-inch subs, it trades refinement and long-term durability reputation for output per dollar.

    About the W65K9D2

    The Rockville W65K9D2 is a 6.5-inch dual 2-ohm car subwoofer from the K9 Series. It is rated for 1000 watts peak, 500 watts program and 250 watts CEA RMS power handling.

    It has a cast aluminum basket with a black sanded finish, a black non-pressed paper cone with stitched reinforcement, a thick foam surround and a polypropylene dustcap. The 2-inch 4-layer ASV voice coils are wound with OFC wire made in the USA and are stable up to 180 degrees Celsius. The motor uses a double-stacked 66 oz magnet with a rubber boot cover, an 8mm T-yoke with a vent hole for heat dissipation, and an 8mm washer.

    Two chrome-plated binding post terminals accept any gauge of wire. A custom Rockville mounting gasket helps seal the subwoofer air-tight when mounted. It can be used in a sealed or a ported enclosure.

    Questions and answers

    What amplifier works with the W65K9D2?
    The dual 2-ohm coils wire to either 1 ohm or 4 ohms. Use an amp that is stable at the load you choose and rated near the sub's power handling.
    What size box does it need?
    It is a 6.5-inch driver, so it fits small sealed or ported enclosures. Check the mounting depth and cutout diameter against your box before buying.
    Is one sub enough?
    For a compact car or truck, one 6.5-inch sub adds noticeable low end. Two subs give more output but need more space and amp power.
    Does it come with a box or amp?
    No. It is sold as the subwoofer driver only, so you supply the enclosure, amplifier and wiring.
    How does it compare with name-brand 6.5-inch subs?
    It aims at more output for the money. Name brands generally offer cleaner sound and better durability reputations.
    Where is the W65K9D2 cheapest?
    At Rockville, for $124.95, as of our latest check.
