K-Array Thunder KS2PW I – White Passive 18-Inch Subwoofer

Product Overview

The K-Array Thunder KS2PW I is a white passive 18-inch subwoofer built for architectural AV installations where the audio system must visually recede into light interiors. Performance-identical to the black KS2P I, this compact 8-ohm installation subwoofer produces 137 dB maximum SPL with response down to 35 Hz, reinforcing column array systems in houses of worship, auditoriums, and design-conscious commercial spaces. Passive operation with 1400 W peak power handling keeps amplification in a centralized rack, and the 8-ohm load allows two cabinets per amplifier channel. Prefer dark hardware? The black KS2P I version is also available.

Product Description

White interiors, light wood, and contemporary architectural finishes are common in modern worship venues and corporate facilities — and a black subwoofer cabinet undermines that aesthetic. The KS2PW I's factory white finish keeps an 18-inch low-frequency cabinet visually quiet against light surfaces, with custom RAL colors available for exact specification matching. Inside is a long-excursion 18-inch neodymium magnet woofer with 3-inch voice coil, covering 35 Hz to a crossover-dependent 150/450 Hz upper limit; the wide upper range gives integrators flexibility when crossing to compact white column elements. At just 34 kg (75 lb), the neodymium-driven cabinet is easy to position and conceal, and the polyurea-coated birch plywood enclosure protects the white finish in active venues. Two SpeakON NL4 connectors accept 2-wire or 4-wire amplifier signal and pass it through to additional loudspeakers. K-Array Kommander amplifiers drive the cabinet with DSP low-pass presets from 150 Hz up to 450 Hz, aligning it with white Kayman, Python, and Kobra columns for a fully color-matched system. Larger rooms can step up to the white 21-inch Thunder KS3PW I.

Key Features

• Architectural White Finish — The factory white cabinet disappears against light interiors and pairs with white K-Array columns for a visually unified installation.
• 18-Inch Neodymium Woofer — A long-excursion 18" driver with 3" voice coil delivers genuine low-frequency extension down to 35 Hz.
• 137 dB Maximum SPL — Output headroom covers worship music, presentations, and event playback in mid-size venues.
• 8-Ohm Impedance for Flexible Loading — Two cabinets run in parallel on a single 4-ohm amplifier channel, simplifying dual-subwoofer system designs.
• 1400 W Peak Power Handling — Passive operation keeps all electronics in the rack for easier service in permanent installations.
• Wide Crossover Range — External DSP low-pass settings from 150 Hz up to 450 Hz accommodate pairing with compact column and satellite speakers.
• Lightweight 34 kg Cabinet — Neodymium magnetics ease handling, hoisting, and concealment during commercial integration.
• Polyurea-Coated Birch Plywood Enclosure — The durable coating preserves the white finish through years of installed service.
• Custom RAL Options — Beyond standard white and black, custom RAL finishes match any architectural color specification.

Typical Applications

• Houses of worship with light interiors requiring music-capable bass reinforcement
• Auditoriums where hardware must match white or custom architectural finishes
• Multi-purpose rooms alternating between speech reinforcement and full-range program
• All-hands rooms and commercial meeting spaces in design-forward facilities
• Government spaces and civic venues with strict aesthetic requirements

Frequently Asked Questions

Which amplifier drives the Thunder KS2PW I?

The KS2PW I is passive and requires external amplification rated for an 8-ohm load with up to 1400 W peak handling. K-Array Kommander amplifiers are the recommended pairing, with DSP presets that manage the low-pass crossover and system alignment.

Can two KS2PW I cabinets share one amplifier channel?

Yes. Two 8-ohm cabinets wired in parallel present a 4-ohm load that most professional installation amplifiers drive comfortably, a common design for symmetrical left-right subwoofer placement.

Will the white finish hold up in busy venues?

Yes. The white finish is applied over a polyurea-coated birch plywood enclosure built to resist scuffs and impacts in permanent commercial installations.

Which K-Array speakers pair with it?

White Kayman, Python, and Kobra column elements are the natural companions for a color-matched system. Browse options in the K-Array collection.

Does it integrate with AV control systems?

When driven by K-Array Kommander electronics, the system supports Q-SYS, Crestron, Control4, and other commercial control platforms, with Dante networking on supported amplifier models.

What warranty and support are included?

K-Array provides a 5-year manufacturer warranty, and Creation Networks backs the product as an authorized dealer with pre- and post-sale support.
