Item Description
Overview
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!

Speakers with a burned voice coil are not returnable for exchange, repair, refund, or credit, as this is not covered by its warranty. No exceptions. Distinct burn odor and/or discolored/black spider around base of cone are characteristic of a burned voice coil. While we do not accept returns of speakers with burned voice coils, they may be returned, postage prepaid, for evaluation.

*AUDITIONING YOUR SPEAKERS
Each speaker order includes the following instructions: To "audition" a speaker without scratching or marking it will require getting into the speaker cabinet and listening to it play without actually mounting it with screws. This can be done by tilting the cabinet back and setting the speaker in place. If the cabinet has bare wire leads, just wrap them around the solder lug connector on the back of the speaker to make the electrical connections. A friend can help hold the speaker in place while you listen to the new speaker. This is, of course, not an optimal way to listen to a speaker, but will give you the opportunity to identify major response problems or poor tonal characteristics prior to mounting.
