Product Details

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!

    I bought this subwoofer and made a 150 litre sealed box with 36mm (2x18) thick mdf and ran it on an 1500 watt amp with a mini dsp for tuning, so far I’m really happy, it seems to perform very well against my svs sb 2000s - I have 2 stacked in a corner and the um18 in the other corner, ive not took any measurements yet but I’m very impressed so far regarding the 25 to 30hz performance. Sound imports were really helpful in providing all the information I needed to make the build and when I ordered, it came super quick so I’m a very happy customer.

    Heb 2 van deze ultimax. Ze gaan diep en nog belangrijker, ze klinken in een gesloten kast veel sneller dan je zou verwachten. Wel zwaar EQ lift onder de 50 herz en een zware versterker gebruiken. Mijn 2 x 450 watt rms versterker haalt nog lang niet het uiterste uit de speaker. Blijft goed klinken tot de limit lampjes aangaan.
