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 2.0 cubic ft. (net internal) with 1 lbs. of Acousta-Stuf polyfill, f3 of 36 Hz with a 0.707 Qtc alignment
• Vented 4.0 cubic ft. (net internal, not including driver or port volume) tuned to 20 Hz with a 10″ wide by 1.5″ high slot port that is 25″ long, which yields an f3 of 19 Hz

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

    :

    Well I finally got to try the famous Ultimax out. I built a 2 cubic foot sealed box, as this sub is for sealed boxes (ported is no good for it) based on is recommended instructions from Dayton. Is it the ultimate sub? No…but at is price point I think it is hard to beat. I would not use it for music, although it pounds really good, but it is defiantly a cinema sub. I still need to get 50 hours on it to judge it more in the music aspect, as a sub of this power caliber needs more break in than the average, but I will probably use these again. My only concern is its RMS rating could be higher, because a Crown XLS-1500 on low-pass bridged almost feels under-powered. Perhaps the Dayton A/B 1000 sub amp would yield better sound quality? I do not give it 5 stars because there needs to be a unicorn in the box with it to get that extra star!
