Built To Move Some Air

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.

Industry Leading Motor Strength

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.

Unmatched Versatility

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.

Feel Maximum Power On The Road

The Ultimax UM15-22 15" Subwoofer delivers more than enough power to rock the road ways. The sub is a perfect pick to add massive low end to your mobile audio speaker build. If you are looking for fast, articulate bass that really fills your car, look no further than the UM15-22.

Not only is the UM15-22 great for car audio, it fits perfectly at home in your theater or listening room. The detailed response and low end strength lets you feel the rumble in your movies and gives you a concert-like music listening experience.

Cabinet Recommendations:

  • Sealed: 3.8 cubic ft. (net internal, not including driver volume) with 3 lbs. of Acousta-Stuf polyfill produces an f3 of 34 Hz with a 0.83 Qtc alignment
  • Vented: 4.5 cubic ft. (net internal, not including driver or port volume) produces an f3 of 24 Hz. Larger cabinets and lower tuning frequencies are possible.
