UL12 Subwoofer: Award-Winning 2500W RMS Dual 1.5 Ohm 12 Car Audio Super-Subwoofer

The CRITICAL MASS UL12 has been rated as the number one subwoofer in Car Audio & Electronics Magazine, earning titles such as “the Best” and “the Perfect Sub”. It has outperformed popular subwoofers from manufacturers like JL Audio, Alpine, Kicker, ORION, Rockford Fosgate, Image Dynamics, Digital Designs, Cerwin Vega Stroker Pro, Phoenix Gold, and many others that did not even make the top 10.

So, what makes the Critical Mass UL12 so extraordinary? Beating other subwoofer manufacturers might seem easy when the tester is an amateur, blogger, enthusiast, or even a lifelong audiophile. However, when the testing engineer is someone like Mr. Vance Dickason, the author of the top-selling Loudspeaker Design Cookbook, then the results become truly meaningful.

In the world of car audio, one can find subwoofers that are lightweight, powerful, efficient, high-quality, or compact. However, only the Critical Mass UL12 manages to excel in all these aspects and surpasses others in both sound quality and sound pressure level (SPL), all within a small 1.35 cubic feet enclosure.

The UL12's reference testing enclosure, weighing less than 40lbs including the subwoofer itself, produced superior sound quality (earning the highest sound quality scores in CA&E history) and delivered more impactful bass than larger, heavier subwoofer combinations weighing over 200lbs. While the UL12 can achieve an impressive 154db SPL in larger enclosures (as verified by James Claridy of Audio Enhancers), its true standout feature is its ability to outperform much larger subwoofers in total output while also fitting into tiny enclosures as small as 0.25 cubic feet.

The UL12 boasts a sensitivity of 97db with coils in parallel, a C.M.G.A.P. NEO-M magnet motor, Ultra-High Temp Dual Coil voice coil type, 4” voice coil diameter, and 1.5 ohm nominal impedance per coil. Its True Carbon Fiber cone and proprietary NEO-M Motor structure allow it to handle 5KW peak power.

This ultimate super subwoofer in terms of sound quality is capable of handling up to 2500W RMS power in small sealed enclosures, making it a remarkable choice for those looking to maximize both performance and space efficiency.
