ePS12-EN54
Measuring 600mm high x 370mm wide x 317mm deep and weighing 18Kg, the ePS12-EN54 combines a high excursion 12-inch LF driver with a 1.7-inch diaphragm HF driver in a trapezoidal cabinet constructed in a bass-reflex design from 15mm Baltic birch plywood. Achieving a peak SPL of 133dB with a frequency range of 60Hz to 20kHz, the ePS12-EN54 features a rotatable asymmetric horn, convenient rigging points on the cabinet top, bottom and back, and two pairs of In/Out connectors on pitch screw terminal blocks with an IP cover.
