K-Array Pinnacle KR102 II – Powered Stereo Column Array System (Black)

Product Overview

The K-Array Pinnacle KR102 II is a powered stereo column array system built for commercial AV installations and portable sound reinforcement in houses of worship, corporate meeting spaces, and multi-purpose rooms. This complete powered PA package pairs one self-powered Thunder KS1 I 12-inch DSP subwoofer and one passive Thunder KS1P I subwoofer with two Kobra KK102 I line array column loudspeakers and the mounting hardware needed for fast deployment. As a portable line array column speaker system with onboard amplification and processing, it removes the need for external racks, making commercial deployment fast for integrators and end users alike. Its slim stainless steel columns deliver intelligible, full-range coverage while staying visually discreet in architecturally sensitive spaces.

Product Description

At the heart of the KR102 II is the self-powered Thunder KS1 I subwoofer, which houses a 12-inch neodymium magnet woofer in a polyurea-coated birch plywood enclosure and drives both the Kobra KK102 I column on its top and the second passive column stack built on the Thunder KS1P I subwoofer. Built-in DSP manages crossover, presets, and system tuning, and the K-array Connect mobile app gives operators a straightforward interface for remote control of DSP parameters during setup and live operation. Each Kobra KK102 I column packs sixteen 2-inch neodymium magnet transducers into a one-meter stainless steel chassis, producing true line array behavior with consistent phase response in both the near field and far field. Vertical coverage spans 7 to 35 degrees with 120-degree horizontal dispersion, so the system projects speech and music evenly across seated audiences without exciting reflective ceilings and rear walls. The included poles, adapters, and angle hardware let a single technician assemble the stereo system in minutes, which suits rental inventories, traveling worship teams, and facilities that reconfigure rooms frequently. K-array publishes control plugins for Q-SYS, Crestron, Control4, and other platforms, so the system integrates into managed commercial AV environments rather than operating as an island.

This listing is the black finish; a white version is available as the K-Array Pinnacle KR102W II. Browse the full K-Array collection at Creation Networks for matching subwoofers, line array elements, and accessories.

The K-array Connect mobile app provides remote control of the DSP parameters, including system presets and tuning, so a technician can adjust the system from anywhere in the room.
