Denovo Audio 2" Ultimax Subwoofer and Cabinet Bundle
About the Cabinet
This particular cabinet is designed specifically for the Dayton Audio 12" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 12-3/8" or less, and a cutout requirement of 11-1/8" or less. For optimum performance with the Ultimax 12" subwoofer, add one pound of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 36 Hz. During the CNC manufacturing process, rabbets and dadoes are cut into the back panel for precise panel alignment. A unique two-piece brace adds superior rigidity without affecting the subwoofer's performance. Both side panels feature 3/4" rabbeted extensions with recesses to perfectly install the first piece of the two-part, double thick baffle. The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 12" Ultimax subwoofer. All that's left to do is finish it to match your décor or paint it to stand out.
Specifications: • Panel thickness: 3/4", front baffle is 1-1/2" • Panel material: Medium Density Fiberboard (MDF) • Finished net cabinet volume (subtracting the double thick baffle, bracing, and subwoofer volume): 2.0 cubic feet • External dimensions: 19" H x 16" W x 20" D • Subwoofer recess: 1/2" • Weight: 41 lbs. • Made in the U.S.A.
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.

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.
