K-Array Pinnacle KR402PW II – White Passive Stereo Line Array System

Product Overview

The K-Array Pinnacle KR402PW II is a white passive stereo line array system engineered for commercial AV installations that need high output from loudspeakers that disappear against light interiors. The system pairs four Python KP102 I stainless steel column elements with two Thunder KS3P I passive 21" subwoofers, all driven and processed by the included Kommander KA104 four-channel DSP amplifier. For integrators specifying a house of worship sound system, auditorium reinforcement, or a multi-purpose room audio installation, this passive column speaker system with amplifier keeps every piece of electronics in the rack for easy service access. Mounting hardware is included, so the package arrives deployment-ready for permanent installation.

Product Description

Each Python KP102 I element is a meter-long, stainless steel column loudspeaker loaded with twelve 3.15" neodymium magnet transducers. The closely spaced drivers produce the long throw and high speech intelligibility characteristic of a pure line array, with controlled 7°–30° vertical dispersion and a wide 90° horizontal pattern that keeps energy on the audience and off reflective ceilings and walls. Stacking two KP102 I elements per side extends vertical pattern control for medium to large rooms, and the white finish lets the slim columns blend into sanctuaries, lobbies, and bright modern meeting spaces.

Low-frequency support comes from two Thunder KS3P I passive subwoofers, each built around a long-excursion 21" neodymium woofer with a 4" voice coil in a compact, lightweight enclosure. The included Kommander KA104 amplifier supplies 4x 2500 W at 4 ohms with onboard DSP and factory presets matched to the KP102 I and KS3P I, so system tuning starts from a verified baseline. Remote control runs through the K-array Connect mobile app, while K-Framework3 software manages multiple units over wired LAN for larger projects. Because the loudspeakers are fully passive, all electronics live in the rack, unlike the self-powered Pinnacle KR402W II, which builds the amplification into a Thunder KS3 I subwoofer. The same passive system in black is sold as the Pinnacle KR402P II, and a black powered variant is available as the KR402 II.

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 draw the eye.
• Complete Passive Stereo Package — The bundle includes four KP102 I line array elements, two KS3P I subwoofers, one Kommander KA104 amplifier, and mounting hardware so integrators can specify one part number per room.
• 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 acoustically difficult rooms.
• Deep, Compact Low End — Each Thunder KS3P I delivers 139 dB peak SPL from a long-excursion 21" neodymium woofer with 2800 W peak power handling at 4 ohms.
• DSP Amplification Included — The Kommander KA104 provides 4x 2500 W at 4 ohms with factory presets for every loudspeaker in the system, plus K-array Connect app control.
• Rack-Based Serviceability — With fully passive loudspeakers, all electronics stay in the equipment rack, simplifying maintenance in ceilings, balconies, and other hard-to-reach mounting positions.
• Control System Integration — K-Array publishes plugins for Q-SYS, Crestron, Control4, Kramer, RTI, Savant, and Symetrix, so the amplifier integrates into existing commercial control infrastructure.
• Five-Year Manufacturer Warranty — K-Array backs its products with a 5-year warranty policy for long-term installation confidence.

Technical Specifications

Frequently Asked Questions

What amplifier drives the KR402PW II, and is it included?

Yes. The system ships with the Kommander KA104, a four-channel DSP amplifier rated at 4x 2500 W into 4 ohms, with factory presets matched to the KP102 I and KS3P I loudspeakers.

How does the KR402PW II differ from the powered KR402W II?

Both systems use four KP102 I columns and 21" Thunder subwoofers in white. The KR402W II builds amplification and DSP into a self-powered Thunder KS3 I subwoofer, while the KR402PW II is fully passive and includes the rack-mounted Kommander KA104, which many integrators prefer when electronics must stay in an equipment room.

Can the KR402PW 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 K-Array mounting hardware, and the KP102 I supports wall, pole, fly, and subwoofer-top mounting through K-Array accessories such as the K-WALL2, K-FLY3, K-JOINT3, and K-FOOT3. 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 makes the system well suited to houses of worship, auditoriums, and government meeting spaces.

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.
