Line source with exceptional SPL, LF and throw capability for stadium and outdoor. New K transducer configuration for smooth horizontal radiation pattern. It features two 15-inch speakers mounted in a bass-reflex enclosure, four 6.5-inch high-efficiency direct radiating speakers, and three 3-inch diaphragm compression drivers coupled to individual DOSC waveguides. The transducers are implemented in a K-shape configuration. The K1 enclosure is based on a 3-way active design with 2 LF sections, 1 MF section and 1 HF section, each one at the nominal impedance of 8ohms.
