      Product details

      Dayton Audio UM15-22 15" 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 3.1 cubic ft. (net internal) with 3 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment
      • Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4" diameter by 26" long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.

       

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

      This is a very, very well built woofer who delivers exactly what it says! Oddly there is no exaggeration in the selling text, And it delivers more. Built towers 40 by 40 cm and 1,2M high wit 2x4"x66cm vents. and it is digging very, very deep in the octaves. It was almost hard to beleive the room analyzer :D going down to 16Hz and feeling it all the way. I have built woofers for 35+ years and this must be the (for the money) best of them! Thanks Soundimports and Dayton! If you build it well you will not be disappointed!!!!
