Dayton Audio UMII12-22 Ultimax II DVC Subwoofer

The Dayton Audio UMII12-22 Ultimax II DVC Subwoofer delivers exceptional low-frequency performance, combining deep, accurate bass with remarkable power handling. Engineered for audiophiles and home theatre enthusiasts, this high-excursion subwoofer is equally at home in sealed or ported enclosures, making it a versatile choice for both dedicated listening rooms and car audio installations. Its robust design ensures distortion-free reproduction of the most demanding soundtrack passages and musical transients.

At the heart of the UMII12-22 lies a dual 2-ohm voice coil configuration, offering flexible wiring options to match a wide range of amplifiers. The 22mm linear excursion (Xmax) enables prodigious cone movement, producing authoritative, room-filling bass without compression. An aluminium basket provides a rigid, non-resonant foundation, while the 88.6dB sensitivity ensures efficient use of amplifier power. With a total Q (Qts) of 0.56 and a mechanical Q (Qms) of 2.75, this subwoofer is optimised for both tight, controlled response and deep extension. The 304.8mm nominal diameter and 285mm cut-out diameter simplify installation, and the eight mounting holes offer secure fitting. Whether for a high-performance home cinema system or a competition-grade car audio setup, the Ultimax II delivers the visceral impact and precision that discerning listeners demand.
