CK-15

CK-15 is a high-performance, compact front-ported speaker designed for use in venues such as party-style KTV, KTV sound reinforcement, bars, nightclubs, and similar locations. It offers an exceptionally smooth frequency response range from 55Hz to 20kHz (-10dB) with an impressively flat phase curve. The CK-15 enclosure features a trapezoidal design, housing a 15-inch woofer on the front and a 1.75-inch Precision Devices ferrite high-frequency driver. The high-frequency driver is accompanied by a 90° (H) × 60° (V) constant directivity horn.

Both the top and sides of the speaker are equipped with M10 mounting holes for suspension installation, while the bottom support frame base serves a variety of purposes. The CK-15 speaker achieves a sensitivity of 98dB and an AES power rating of 600W. It employs a compact enclosure design with front-ported ports. This design effectively reduces the group delay in the low-frequency range, enhancing the perception of speed in the low frequencies and mitigating nonlinear distortion. As a result, it achieves a harmonious balance between speed, power, and richness in the low frequencies, resulting in a dynamic and elastic low-frequency effect that excels in any environment.

The enclosure is meticulously constructed using 15mm multi-layer plywood and finished with a durable black water-based paint. The rear panel features two NL-4 four-core sockets for connections (1+1- input, 2+2- link). The rotatable logo enhances suitability for various speaker angles. The black perforated iron grille is lined with acoustic fabric to effectively combat moisture and dust, all while safeguarding the transducer components.
