The UX-218A joins the new range of UX Series subwoofer systems in both powered and passive versions. The UX-218A makes use of two 18UXN4 transducers. The new loudspeaker designed and manufactured by DAS offers impressive features such as a 4” sandwich split winding voice coil, a remarkable 52 mm peak to peak excursion, and a powerful FEA optimized neodymium magnet assembly. Thanks to the double silicon spider, the 18UXN4 controls the moving mass with high linearity. An aluminum demodulating ring benefits lower distortion and effective ventilation of the voice coil gap provides for a high thermal rating, and reduced power compression. The UX-218A amplifier offers 2 x 1700 Wcontinuous and incorporates the latest in Class D power amplification.

A high efficiency, low consumption universal power supply with Power Factor-Correction (PFC) allows for fail safe use worldwide. State of the art electronic design such as the fixed frequency switch mode output stage provides for the highest grade of audio accuracy. A comprehensive set of ”smart” protections include thermal, over current, short circuit and overload on the output, clip limiter and high frequency protection keeping the amp and acoustic components safe.
