The Dayton Audio Ultimax DVC subwoofer provides over 2″ of peak-to-peak excursion, the Ultimax 18 sweeps over 6L of air with each stroke. 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 aluminium 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 1000 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.
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.
