At Prolight + Sound 2015 in Frankfurt, K-array (hall 8, booth A60) has launched a new line of Concert Series line array loudspeakers, including KH2, KH3, KH5 self-powered full-range models and the KS5 self-powered subwoofer. All offer a very thin profile and are designed for a range of touring, portable and installed sound applications.
All full-range models are equipped with the company’s proprietary “slim array technology” (S.A.T), fully controlled by onboard DSPs for very detailed beam steering and operational flexibility. Each unit has discrete DSP channels and proprietary beam steering technology to provide the ability to tailor to meet any application, while also helping in controlling sound spillover.
All components are driven by an onboard multichannel Class D amplifier. Each loudspeaker is equipped with an onboard touch screen with matrix control, with RS485 and USB connectivity provided for remote control.
Full-range arrays are flown vertically, but each unit has the ability to be tilted totally independent. The result is “straight array” (vertically), but one that has a wavefront with the desired curvature from a vertical cluster. Further coverage precision is obtained via the onboard DSP channels in each loudspeaker, each designed to load FIR and delays to achieve highly accurate steering.
The KH2 incorporates two 8-inch neodymium woofers (with 2.5-inch voice coils) joined by two x 1.4-inch compression drivers (also with 2.5-inch voice coils).
The KH3 is loaded with two 12-inch neodymium woofers (with 2.5-inch voice coils) and two 1.4-inch compression drivers (also with 2.5-inch voice coils).
The KH5 has two 15-inch neodymium woofers (with 3-inch voice coils and four 1.4-inch compression drivers (with 2.5-inch voice coils).
And, the KS5 subwoofer comprised of 2 x 21” Neodymium magnet woofer with 5.5” voice coil
