        Product description

        Dayton Audio's Ultimax Series DVC subwoofers are purpose-built to move air and create clean, articulate, fast bass. Experience the apex of subwoofer design.



        • Thick, one-piece Nomex honeycomb covered cone with woven heavy-duty glass-fiber
        • Tall-boy rubber surround for extra-long linear excursion without reducing cone surface area
        • 600 watts RMS power handling
        • Copper shorting rings and cap reduce distortion due to inductance variations
        • Dual 2 ohm, 2-layer copper voice coils
        • Large vented pole piece and under-spider venting
        • Black anodized aluminum former and black pole improves heat dissipation


        Product details

        Dayton Audio UM12-22 12" Ultimax DVC Subwoofer 2 ohms Per Coil


        If you want outrageous amounts of bass, you gotta move some air

        The Ultimax Series of dual voice coil subwoofers, from Dayton Audio, are not for the faint of heart. Built using the latest in subwoofer technology, Ultimax subwoofers are the pinnacle of low frequency driver design. An Ultimax subwoofer tests the strength of your foundation with fast, articulate, gut-wrenching bass.


        The versatility you need for mobile, home, or pro subwoofer excellence

        Dual 2 ohm voice coils allow for stereo 2 ohm and mono 1 ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a benign 4 ohm load for greater amplifier compatibility.


        Built to produce massive low frequency output and keep on doing it

        To improve power handling, increase thermal management, and reduce power compression, Dayton Audio designed the Ultimax Series with large black anodized formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.


        Over 1-1/2" of travel (3/4" Xmax) is kept completely linear through the use of dual spiders that also limit distortion and rocking modes. "Tall-boy" rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibers creating ultra-still cones that resist deformation.


        A strong motor takes you to wherever you want to be

        A large copper sleeve and copper pole cap in the motor reduce energy storage from inductance, with the side benefit of lowering distortion for "faster" response. Large dual-stacked, high-energy magnets handle the heavy lifting and bring Qts down to a level where Ultimax subwoofers can be used in vented or sealed cabinets and enclosures.

        Cabinet recommendations:

        • Sealed: 1.5 cubic ft. (net internal, not including driver volume) with 1 lbs. of Acousta-Stuf polyfill produces an f3 of 36 Hz with a 0.9 Qtc alignment
        • Vented: 2 cubic ft. (net internal, not including driver or port volume) produces an f3 of 25 Hz


        Note: All parameters derived with voice coils wired in series.
