K-Array Thunder KS1W I – White Self-Powered 12" DSP Subwoofer

Product Overview

The K-Array Thunder KS1W I white powered subwoofer brings the system-core capabilities of the Thunder KS1 I to design-sensitive interiors that call for a white 12 inch self-powered subwoofer. Built around a 12" neodymium woofer and a 4x 1500 W @ 4-ohm Class D amplifier module with DSP, this architectural white subwoofer installation choice powers itself and connected K-Array passive loudspeakers through onboard speaker outputs. For houses of worship, bright modern meeting spaces, and venues with light architectural palettes, the KS1W I delivers compact powered subwoofer performance for commercial integration without dominating the room visually.

Product Description

Functionally identical to the black Thunder KS1 I, the KS1W I pairs a sealed (no bass reflex) polyurea-coated birch plywood enclosure with a 12" neodymium magnet woofer, reaching down to 35 Hz and producing up to 134 dB peak SPL. Its four-channel 1500 W @ 4-ohm amplifier with integrated DSP feeds both the internal driver and two SpeakON NL4 power outputs, so a single white cabinet can amplify and process K-Array passive mid-high satellites or additional passive subwoofers — a complete system hub that removes the need for a separate amplifier rack in the equipment closet.

Signal connectivity includes dual XLR inputs and link outputs supporting analog or AES3 digital audio, RJ45 networking, four USB-A ports, and powerCON TRUE1 TOP mains. The built-in Web App, K-Framework3 software, and the K-array Connect mobile app give integrators and operators remote control of DSP parameters and signal routing, while published plugins for Q-SYS, Crestron, Control4, and Dante licensing tie the subwoofer into managed commercial AV control environments. At 21.6 kg the cabinet installs quickly, and the optional K-POLE2 accessory mounts a satellite speaker above it for elegant column-style systems. Need black instead?

Key Features

• White Architectural Finish — The factory white cabinet blends into light interiors, with Custom RAL matching available for exact color coordination.
• 4x 1500 W @ 4-Ohm Amplifier Module — The integrated Class D amplifier powers the subwoofer and external passive K-Array cabinets from one enclosure.
• Power Outputs for Passive Speakers — Two SpeakON NL4 speaker outputs let the KS1W I drive passive satellites and subwoofers, making it the core device of the system.
• Onboard DSP with Presets — DSP-controlled crossover (low pass at 150 Hz, preset dependent) and factory presets deliver matched tuning for K-Array satellite series.
• 35 Hz Low-Frequency Extension — Response of 35 Hz to 150/450 Hz (-6 dB, crossover dependent) with 134 dB peak SPL reinforces full-range program audio.
• Analog and AES3 Digital Connectivity — Dual XLR inputs and link outputs carry analog or AES3 digital signal between system devices.
• Remote Management Over the Network — RJ45 networking with the built-in Web App, K-Framework3, and K-array Connect app supports remote DSP control and monitoring.
• Commercial Control Integration — Plugins for Q-SYS, Crestron, Control4, Symetrix, and Dante licensing connect the subwoofer to managed AV control systems.
• Lightweight Sealed Cabinet — The 21.6 kg polyurea-coated birch enclosure with no bass reflex simplifies handling and rigging during installation.

Typical Applications

• House of worship sanctuaries with light interiors needing discreet low-frequency reinforcement
• Commercial meeting space and all-hands room systems where the subwoofer doubles as system amplifier
• Auditorium and multi-purpose room installations with white or custom-color architecture
• Broadcast studio sets where a white cabinet matches scenic design
• Government space and training room AV systems requiring networked remote control

Technical Specifications

Frequently Asked Questions

Is the KS1W I technically different from the black KS1 I?

No. The KS1W I is the same self-powered 12" subwoofer with DSP and power outputs in a white factory finish; all acoustic and electronic specifications are identical to the black Thunder KS1 I.

Can it power white K-Array satellite speakers for a fully white system?

Yes. The two SpeakON NL4 power outputs from the onboard 4x 1500 W amplifier drive K-Array passive loudspeakers, and most K-Array satellites are offered in white or Custom RAL, so an all-white system can run entirely from the KS1W I.

How do operators control the DSP after installation?

DSP parameters and signal routing are accessible through the built-in Web App, K-Framework3 desktop software, or the K-array Connect mobile app over the network, so adjustments do not require physical access to the cabinet.

Does the KS1W I work with Q-SYS, Crestron, or Dante environments?

Yes. K-Array publishes control plugins for Q-SYS, Crestron, Crestron Home, Control4, Symetrix, and RTI, and offers Dante licensing for networked audio integration in managed commercial AV systems.

What inputs does it accept from a DSP or mixer?

The dual XLR line inputs accept analog or AES3 digital signals, with matching XLR link outputs to feed additional Thunder subwoofers or system electronics downstream.

What warranty and support come with this subwoofer?

K-Array products are covered by the manufacturer's 5-year warranty policy, and Creation Networks provides commercial AV system design help, speaker pairing guidance, and post-sale support.
