KORA-A

KORA is a self powered 2 kW, compact dual 8” line array system. Designed for medium size projects, boasting extreme SPL and extended low frequency capabilities for its compact design when used with the KORA-SUB flying subwoofer. KORA integrates a 4-point rigging system into both models, making KORA-A a flexible solution for both install and touring alike.

Using high-power Class D amplifiers with integrated DSP, this self-powered cabinet has 4 dedicated amplification channels allowing each component to be directly driven, this removes crossover distortion and increases audio quality. Full FIR filtering adds further detail and definition, this coupled with RMS and Peak limiters ensure the system stays within safe working parameters.

Featuring 2 x 8” proprietary woofers in a reflex tuned enclosure with dual 4” neodymium planer wave drivers. An SPL of 142dB (peak), or in a concert array of 8 boxes SPL of 155dB (peak). KORA-A’s frequency response is from 74 Hz to 21 kHz. This can be extended down to 28Hz when used with KORA-S subwoofer. An exposed phase plug design provides a smooth linear response and dispersion free of lobes over the entire frequency range. The waveguide generates a symmetrical horizontal dispersion of 100° x 12° vertical.

Made of high-grade Baltic birch plywood coated in tough Polyurea ensures mechanical and acoustical integrity. A fully integrated 4-point rigging system designed with various angles of up to 12° per cabinet, which ensure a perfect acoustic coupling between multiple cabinets forming an array. The Kora array frame is a single and multi-point flying frame which is perfect for ground stacking or flying KORA-A, KORA-S and self-powered versions. The same hardware can be used when ground-stacking KORA-A on TR-118/218.

Each KORA-A is a lightweight 22.4 Kg reducing transportation and rigging weight. With a system hang of 9 Kora flying on a Kora-array frame weighs 222 kg. which is far below most maximum load points from small portable stages and theatres. Each Kora Array frame K-AF weighs 27.23 kg.

The robust enclosure has a unique exposed phase plug design front, hardwearing Polyurea paint finish and two butterfly handles on each side.

The rear connection plate has an input (female XLR), a link (male XLR) connector and a powerCON®True1 connector input and link fitted as standard.
