K-Array Pinnacle KR404PW II – White Passive Stereo Line Array System

Product Overview

The K-Array Pinnacle KR404PW II is a white-finish, large-format passive stereo line array system designed for architecturally sensitive venues where the audio system must visually disappear into light-colored interiors. It pairs eight Python KP102 I stainless steel line array elements with four Thunder KS3P I passive 21" subwoofers and a Kommander KA208 eight-channel DSP amplifier, making it a complete white line array installation package for houses of worship, auditoriums, and modern corporate all-hands rooms. The discreet column form factor delivers high-output, high-intelligibility coverage without compromising interior design. Mounting hardware is included for permanent commercial AV deployment.

Product Description

Functionally identical to the black KR404P II, the KR404PW II provides the same acoustic platform in a white finish that blends with plaster, stone, and contemporary architectural surfaces. Each Python KP102 I element is a meter-long column loaded with twelve 3.15" neodymium magnet transducers, delivering pure line array behavior: long throw, high speech intelligibility, 7°–30° controlled vertical dispersion, and 90° horizontal coverage. Stacking two elements per array position extends pattern control for deep seating areas and balconies.

Low-frequency reinforcement comes from four Thunder KS3P I passive subwoofers, each built on a long-excursion 21" neodymium woofer with a 4" voice coil and 2800 W peak power handling at 4 ohms. The included Kommander KA208 delivers 8x 2500 W at 4 ohms with onboard DSP and factory presets for every component, and because the loudspeakers are passive, all electronics remain rack-mounted and serviceable away from the architecture. Remote control runs through the K-array Connect mobile app, K-Framework3 manages multiple amplifiers over wired LAN, and published plugins integrate the platform with Q-SYS, Crestron, Control4, and other commercial control systems.

Frequently Asked Questions

Is the white finish acoustically identical to the black KR404P II?

Yes. The KR404PW II uses the same KP102 I elements, KS3P I subwoofers, and KA208 amplifier as the black system; only the finish differs.

Are the white columns suitable for visible installation in sanctuaries and historic interiors?

That is the intended use case. The slim, meter-long white columns are designed for architecturally sensitive environments where the sound system must remain visually unobtrusive against light surfaces.

What amplifier and processing are included?

The Kommander KA208 eight-channel DSP amplifier ships with the system, rated 8x 2500 W into 4 ohms, with factory presets for the KP102 I and KS3P I and remote control through the K-array Connect app.

Can the system integrate with our building control platform?

Yes. K-Array publishes plugins for Q-SYS, Crestron, Control4, Kramer, RTI, Savant, and Symetrix, and K-Framework3 software manages multiple amplifiers over a wired LAN.

How is the system mounted?

Mounting hardware is included, and the KP102 I supports wall mounting, flying, and subwoofer-top or pole mounting through K-Array accessories. Final rigging design should come from a qualified AV installer.

What warranty applies, and who supports the purchase?

K-Array provides a 5-year manufacturer warranty, and Creation Networks supports commercial buyers with quoting, specification, and post-sale assistance through the K-Array collection.
