Dayton Audio UM18-22 18" Ultimax DVC Subwoofer 2 ohms Per Coil
If you want outrageous amounts of bass, you gotta move some air
With the UM18-22 Ultimax 18" driver, Dayton Audio has taken everything about the respected Dayton Audio Ultimax subwoofers to the extreme! Providing over 2" of peak-to-peak excursion, the Ultimax 18 sweeps over six liters of air with each stroke! Truly not for the faint of heart!
An audio bulldozer with the finesse of a sports car
Like the rest of the Ultimax series, the UM18-22 plays it clean, low, fast, and LOUD. Designed to excel in either sealed or vented enclosures, it features an ultra-powerful triple stack of high-grade ferrite ceramic magnets for ultra-high force and exceptional control, plus dual aluminum shorting rings above and below the magnetic gap for minimized inductance, "faster"-sounding bass response, and perfect magnetic symmetry. The voice coil diameter has been increased to 3 inches, for even more thermal dissipation area that allows the 18" model to withstand 1,000 watts of punishing bass power continuously without thermal fatigue. Dual 2-ohm voice coils allow for stereo 2 ohm operation, or mono operation in 1 ohm or 4 ohm configurations, for true design flexibility.
Built to produce massive low frequency output and keep on doing it
The huge 18" Nomex honeycomb composite curved cone features woven fiberglass outer skins for the ultimate in rigidity and resistance to damage, while the "tall-boy" rubber surround with integral gasket supports extreme stroke with linearity and durability. Dual 8" spiders are mirror-imaged, to keep the 2" of excursion completely linear and provide cancellation of distortion due to compliance asymmetry, for ultra-low mechanical distortion even at the outer limits of travel. And it's all held in perfect alignment by a rigid cast aluminium 12-spoke frame, for stability in any mounting position.
Put your home's construction to the test with the phenomenal bass output of this 18" beast!
Feel Maximum Power On The Road

Build Your Own Personal Cinema
Not only is the UM18-22 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.
- Sealed (home theater/music): 4 cubic ft. (net internal, not including driver volume) produces an f3 of 33 Hz with a 0.85 Qtc alignment
- Vented: 6 cubic ft. (net internal, not including driver or port volume) produces an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.
Note: All specifications are derived with voice coils wired in series.
