K-Array Pinnacle KR402W II – White Powered Stereo Line Array System

Product Overview

The K-Array Pinnacle KR402W II is a white powered stereo line array system designed for architecturally sensitive commercial AV installations where the loudspeakers must match bright interiors. The package pairs four Python KP102 I stainless steel column elements with a self-powered Thunder KS3 I subwoofer and a passive Thunder KS3P I subwoofer, all finished in white. Because amplification and DSP are built into the KS3 I, this self-powered column speaker system requires no external rack amplifier, which keeps a house of worship sound system or multi-purpose room audio installation simple to deploy. K-JOINT3 and K-FOOT3 mounting hardware is included.

Product Description

At the heart of this white architectural line array is the Thunder KS3 I, a compact active subwoofer with a 21" neodymium magnet woofer and an onboard Class D amplifier module rated at 4x 2500 W into 4 ohms with built-in DSP. The KS3 I drives the pair of Python KP102 I columns mounted on its top and also powers the second stack, where a passive Thunder KS3P I subwoofer supports the remaining two KP102 I elements to complete the stereo pair without any rack electronics.

Each Python KP102 I element is a meter-long stainless steel column loaded with twelve 3.15" neodymium magnet transducers, producing the long throw and high speech intelligibility of a pure line array with controlled 7°–30° vertical dispersion and a 90° horizontal pattern. The white finish lets the slim columns disappear against light walls in sanctuaries, lobbies, and modern meeting spaces. The onboard DSP provides channel grouping, a 3-band parametric input EQ, an 8-band parametric output EQ with selectable filter types, dynamic limiters, freely assignable signal routing, and up to 230 ms of channel delay, all controlled through the K-array Connect mobile app or K-Framework3 software over wired LAN. The same powered system in black is available as the Pinnacle KR402 II, and rack-amplified passive versions are sold as the KR402PW II in white and the KR402P II in black.

Key Features

• White Architectural Finish — Factory white columns and subwoofers blend into light interiors such as sanctuaries, galleries, and modern corporate spaces where black loudspeakers would stand out.
• Self-Powered System Core — The Thunder KS3 I integrates a Class D amplifier rated at 4x 2500 W into 4 ohms with built-in DSP, eliminating the need for an external rack amplifier.
• Complete Powered Stereo Package — One KS3 I active subwoofer, one KS3P I passive subwoofer, four KP102 I line array elements, four K-JOINT3 connectors, and two K-FOOT3 adapters ship under a single part number.
• Pure Line Array Performance — Each KP102 I uses twelve closely spaced 3.15" neodymium transducers to achieve long throw and high intelligibility with 134 dB peak SPL per element.
• Controlled Coverage Pattern — The 7°–30° vertical by 90° horizontal dispersion keeps sound focused on listeners and reduces reflections in reverberant rooms.
• Deep Low-Frequency Extension — Both 21" neodymium subwoofers extend bass response down to 30 Hz from compact, polyurea-coated birch plywood enclosures.
• App and Network Control — The K-array Connect mobile app handles remote control, while K-Framework3 and the built-in Web App manage units over wired LAN, with plugins for Q-SYS, Crestron, Control4, Kramer, RTI, Savant, and Symetrix.

Technical Specifications

Frequently Asked Questions

Does the KR402W II require a separate amplifier?

No. The Thunder KS3 I subwoofer contains a Class D amplifier rated at 4x 2500 W into 4 ohms with built-in DSP, and it powers the passive KS3P I subwoofer and all four KP102 I columns. If your design calls for rack-based electronics, the passive white Pinnacle KR402PW II ships with a Kommander KA104 amplifier instead.

Will the white finish match our interior?

The system ships in K-Array factory white, and K-Array also offers custom RAL colors and premium finishes for projects that need an exact architectural match. Contact Creation Networks for custom finish quotes and lead times.

Can the KR402W II integrate with our existing control system?

Yes. K-Array provides plugins for Q-SYS, Crestron, Control4, Kramer, RTI, Savant, and Symetrix, and the K-array Connect mobile app handles day-to-day remote control of DSP parameters and routing.

How are the KP102 I columns mounted?

The package includes four K-JOINT3 joining brackets and two K-FOOT3 adapters for standing the columns on top of the Thunder subwoofers or a 35 mm pole. Wall and fly options such as the K-WALL2 and K-FLY3 are available separately, and final rigging should be specified by a qualified installer.

Is this system suitable for speech-critical rooms?

Yes. The pure line array geometry of the KP102 I is designed for high speech intelligibility and long throw, which suits houses of worship, auditoriums, government meeting spaces, and all-hands rooms.

What warranty applies to this system?

K-Array products carry a 5-year manufacturer warranty. Creation Networks supports the sale with pre- and post-installation assistance for commercial AV buyers.
