Dayton Audio UM12-22 12" Ultimax DVC Subwoofer

The Dayton Audio Ultimax UM12-22 12" Subwoofer is a formidable audio component engineered to deliver deep, accurate low-frequency extension with exceptional control. Designed for audiophiles and home theatre enthusiasts, this subwoofer excels in both sealed and ported enclosures, providing the foundation for immersive soundscapes that bring music and film to life. Whether you are building a dedicated home cinema system or upgrading a high-fidelity stereo setup, the UM12-22 ensures every bass note is rendered with precision and authority.

At the heart of this subwoofer lies a robust Nomex cone, chosen for its rigidity and lightweight properties, which allows for high-excursion performance without distortion. With a maximum linear excursion (Xmax) of 19mm and a displacement volume (Vd) of 932.7, it moves substantial air to produce powerful, room-filling bass. The 2.9 mechanical Q (Qms) and 1.05 electrical Q (Qes) combine to a total Q (Qts) of 0.77, offering excellent damping and transient response. A copper voice coil with an inductance of 0.78mH and a DC resistance of 3.7 ohms ensures efficient power handling, while the 86.7dB sensitivity at 2.83V provides ample output. The subwoofer’s 314.5mm diameter and 191mm depth require a cutout of 272.5mm, secured by eight mounting holes for a solid installation. This Ultimax model is the definitive choice for those seeking uncompromising low-end performance.
