Overview

The new K-array KK52 is a passive speaker system comprised of eight 2” neodymium magnet transducers housed in an elegant and sturdy stainless steel chassis. The vertical dispersion pattern can be switched for wide or narrow coverage, allowing for a great variety of applications. The eight closely spaced cone drivers provide true line array characteristics - phase coherence, low distortion and focused listening in both the near field, and at a distance from the speaker.

•  A variety of rigging accessories provides many linking and hanging options for the KK52 (0.5 meter) and the larger (1 meter) KK102 to be combined in vertical and horizontal line array configurations to satisfy many different venue requirements during temporary events and for permanent installations.
•  For easier use and integration with other speakers or amplifiers, the KK52 allows the user to select two different values of impedance (16Ω – 64Ω).
• At 64Ω as many as 8 KK52 speakers can be powered off a single amplifier channel at 8Ω (up to 16 elements @ 4Ω), which eliminates the need of 70 V amplifiers for wider distributed installed systems.
•  The KK52 is able to reproduce the whole vocal frequency range with high intelligibility, starting from 150 Hz. Integrating one of the Redline series powered subwoofers (KMT12, KMT18, KMT21), configured with specific presets for the KK52 assures excellent coverage of the entire musical frequency range.
• The K-array KA amplifier series have pre-sets optimized for KK52 use that can be uploaded from a computer.
• All Kobra KK52 components are designed by the K-array R&D department and custom-made under the K-array quality control system.

1) Mounting screw holes. Most K-array mounting or flying accessories are designed to screw into the speakers using these holes. The KK52 is equipped with two screw holes, while the KK102 is equipped with four.

2) Impedance switch. Selects the impedance of the speaker. Impedance must be set to high (64 Ω for KK52 and 32 Ω for KK102) when speakers are driven by KMT active modules. Low impedance may be used when speakers are driven by most KA series amplifiers (KA3, KA7, KA10). Please refer to your amplifier’s specifications to select the correct speaker impedance for your configuration.

3) Coverage switch. Selects the vertical dispersion of the speaker. Flood coverage sets a wide vertical diffusion angle of 60° (KK52) / 35° (KK102). Flood coverage is suggested for single speakers in diffused (image 1) short throw applications, to obtain maximum diffusion with a minimum footprint. Spot coverage sets a narrower vertical diffusion angle of 10° (KK52) / 7° (KK102). Spot coverage is recommended for long throw or monitoring applications (image 2). In most multi-speaker applications, set coverage to Spot (image 3). A combination of Flood and Spot may also be effective for downfill applications (image 4).
