Dual 2 ohm, 2-layer copper voice coils. Large vented pole piece and under-spider venting.
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! 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.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. 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.
