Measuring 423mm high x 250mm wide x 227mm deep and weighing 8.1Kg, the ePS8-EN54 combines a high excursion 8-inch LF driver with a 1.4-inch diaphragm HF driver in a trapezoidal cabinet constructed in a bass-reflex design from 15mm Baltic birch plywood. Achieving a peak SPL of 128dB with a frequency range of 80Hz to 20kHz, the ePS8-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.
