Product details

Dayton Audio UM8-22 8" 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 1-1/4" of travel (.67" 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. The thick, one-piece Nomex honeycomb cone is covered with woven, heavy-duty glass fibers creating an ultra-stiff surface that resists 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: 0.8 cubic ft. (net internal, not including driver volume) produces an f3 of 43 Hz with a 0.74 Qtc alignment
Vented: 1 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.

Sound imports are fantastic I swapped a JL 8w3 that had a blown coil for a Dayton UM8-22 and this thing thumps could even be better than the JL at less than half the price.
