Powerful bass

The Ultimax range of double coil subwoofers from Dayton Audio is the guarantee of powerful bass. Designed using the latest subwoofer technology, the Ultimax is the ultimate low frequency driver for dynamic, accurate and deep bass.

A polyvalent HP

The Double 2 Ohm coils allow the use of 2 Ohm stereo or 1 Ohm mono configurations for high current connection in Car Audio or on professional amplifiers to extract maximum power. For home use, 4 Ohm wiring is preferred for greater compatibility with amplifiers.

Designed to produce massive low frequencies

To improve power support, thermal management, and reduce compression, Dayton Audio designed the Ultimax range with an anodized structure, open polarized parts, ventilation under the spider, and double layer coils.

The UM15-22 offers a linear excursion (Xmax) of 19mm totally linear thanks to the use of a double spider, also limiting distortion. The rubber suspension with integrated gaskets maintains the diaphragm surface in moments of high travel. Nomex honeycomb diaphragms are covered with high-strength, woven fiberglass that allows the diaphragm to resist deformation.

A powerful motor to sublimate your music

In the motor, a copper strapping and a copper pole cover also reduce the energy storage of the inductance, with another positive effect of reducing distortion for a faster response. The two very powerful stacked magnets push the Qts (Total Quality Coefficient) to a level that allows the Ultimax to be used in open or closed boxes.
