The UX-218A makes use of two of the newly developed 18UXN4 transducers. The loudspeakers incorporate 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 aluminium demodulating ring benefits lower distortion and the effective ventilation of the voice coil gap provides for a high thermal rating, and reduced power compression. The speaker has an AES power handling capacity of 1,100 W.
The amplifier powering the UX-218A has an output of 2 x 1700 W 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. The enclosure is manufactured using birch plywood. The enclosure is finished with the tough ISO-flex exterior coating and a punched steel grille protects the speaker components. The UX-218 is the version designed for external amplification.
