The PK CX215-90 wide coverage, self-powered, two-way loudspeaker offers precise high output capability in a compact, efficient enclosure. Each powered cabinet houses a high-efficiency 1500 watt Class-D amplifier with built-in DSP. Innovative post-filter feedback class-D topology achieves ruler-flat frequency response, low distortion and high damping across the audio band. These amplifiers use the latest generation power MOSFET transistors and highly optimized output stage for up to 95% efficiency, allowing quiet fan-less operation. The high frequency section consists of a 3″ titanium diaphragm compression driver coupled to a 90/40 rotatable horn with outstanding pattern control. A 1200w high power 15″ low/mid transducer with a 4″ voice coil and an extremely powerful external neodymium magnet assembly assure high flux concentration, low power compression and excellent heat exchange, allowing for seamless midrange and extended low frequency response. Convenient quick fly rigging provides efficient, arrayable flown configurations. The cabinet is constructed from 100% void-free Baltic birch and coated in the industry’s toughest EXLPolyurea finish. Perforated metal black grills lined with acoustic black foam further enhance the weather resistant properties of double-treated transducer cones.
