The high-frequency speaker array is comprised of 10 small-diameter 1.5-inch speakers. By adopting a J-curve array configuration, the high-frequency unit achieves vertical coverage of 30 ° across a span of 170 °. With such a long, 10-driver array design the DXL1K can deliver clear, high quality sound consistently over longer distances, projecting uniform, high-quality sound from the front to the rear of the audience.
