K-Array Rumble KU210W – White Ultra-Slim Stainless Steel Passive Subwoofer

Product Overview

The K-Array Rumble KU210W is the white-finish version of K-Array's medium-format ultra-slim passive subwoofer, specified when the cabinet must blend into light walls, ceilings, and architectural finishes in conference rooms and commercial interiors. Just 150 mm (5.9 in) deep, this low-profile installation subwoofer pairs a 10-inch long-excursion neodymium woofer with a 10-inch passive radiator for 127 dB peak SPL and 2 x 160 W power handling. Its IP54-rated stainless steel enclosure also suits outdoor architectural AV integration. A black KU210 version is also available.

Product Description

In rooms finished in white plaster, gypsum, or painted millwork, a black subwoofer becomes the most visible object on the wall. The KU210W solves that by matching the surface it mounts against, delivering medium-format bass from a 500 x 282 x 150 mm cabinet that surface-mounts, hides under furniture, or disappears entirely into the wall with the white K-WF210W flush-mount accessory. Acoustically it is identical to the black KU210: a sealed passive-radiator design that keeps dust and moisture out while the long-excursion woofer maintains linear travel down to 40 Hz with minimal residual noise. The double voice coil provides selectable 4-ohm or 16-ohm operation, allowing up to four cabinets per 4-ohm amplifier channel across distributed zones. K-Array Kommander amplifiers carry a dedicated KU210 preset that applies the suggested 150 Hz low-pass crossover and aligns the subwoofer with white Vyper, Lyzard, or KZ14 satellites for a fully color-matched commercial system. White K-WALL2W brackets and K-PMOUNTW pole adapters keep mounting hardware consistent. For more output in white, see the Rumble KU212W; for smaller rooms, the Rumble KU26W.

Key Features

• Architectural White Finish — The factory white enclosure blends into light interior surfaces, with custom RAL colors available for exact specification matching.
• Ultra-Slim 150 mm Cabinet Depth — The 500 x 282 x 150 mm profile mounts flat against walls or under furniture where conventional subwoofers would intrude.
• 10-Inch Long-Excursion Woofer with 10-Inch Passive Radiator — The sealed radiator-loaded design delivers controlled bass from 40 Hz without port noise or ingress paths.
• 127 dB Peak SPL with 2 x 160 W Power Handling — Output covers medium-sized conference rooms, training rooms, and distributed commercial zones.
• Selectable 4/16 Ohm Impedance — The double voice coil supports up to four units per 4-ohm amplifier channel for efficient multi-room wiring.
• White In-Wall Flush-Mount Option — The K-WF210W accessory recesses the cabinet fully into the wall for invisible low-frequency reinforcement.
• IP54 Weather Resistance — The stainless steel construction qualifies the white cabinet for covered outdoor and architectural exterior installations.
• Matched Kommander Amplifier Presets — Dedicated DSP presets align the KU210W with white Vyper, Lyzard, and KZ14 satellites for a color-consistent system.

Frequently Asked Questions

Is the KU210W acoustically identical to the black KU210?

Yes. The white finish is cosmetic only; drivers, enclosure, frequency response, power handling, and impedance options match the black KU210 exactly.

Which amplifier should drive the KU210W?

Any professional amplifier with a low-pass crossover near 150 Hz will work, but K-Array Kommander amplifiers are recommended because their dedicated KU210 preset manages crossover and alignment against K-Array satellites automatically.

Can the KU210W be flush-mounted in a wall?

Yes. The white K-WF210W accessory recesses the cabinet into the wall cavity for fully concealed bass in boardrooms, lobbies, and architectural spaces; black and custom RAL versions are also available.

Can I keep the entire system white?

Yes. K-Array offers white Vyper, Lyzard, and KZ14 satellites plus white K-WALL2W and K-PMOUNTW mounting hardware, with custom RAL options for exact color matching. See the K-Array collection.

How many KU210W units can share one amplifier channel?

With the double voice coil set to 16 ohms, up to four cabinets run in parallel on a single 4-ohm amplifier channel, reducing amplifier count across distributed meeting room zones.

What warranty applies?

K-Array products carry a 5-year manufacturer warranty, supported by Creation Networks as an authorized dealer with commercial AV system design assistance.
