K-Array Rumble KU210 – Ultra-Slim Stainless Steel Passive Subwoofer (Black)

Product Overview

The K-Array Rumble KU210 passive subwoofer delivers medium-format low-frequency reinforcement for conference rooms, training rooms, and commercial AV installations where only 150 mm (5.9 in) of depth is available. This ultra-slim installation subwoofer combines a 10-inch long-excursion neodymium woofer with a 10-inch passive radiator to reach 127 dB peak SPL with 2 x 160 W power handling in a sealed stainless steel enclosure. IP54-rated weather resistance also qualifies it as an outdoor commercial subwoofer. This is the black finish; a white KU210W version is also available.

Product Description

The KU210 occupies the sweet spot of the Rumble line for corporate and institutional integration: enough output for medium-sized rooms, in a 500 x 282 x 150 mm cabinet that mounts on a wall, recesses into it with the K-WF210 in-wall accessory, or hides under furniture without intruding on the space. The passive radiator replaces a reflex port, sealing the enclosure against dust and moisture while the long-excursion 10-inch woofer maintains linear travel with minimal residual noise. The double voice coil offers selectable 4-ohm or 16-ohm impedance, so integrators can parallel up to four cabinets on a single 4-ohm amplifier channel across distributed zones. K-Array Kommander amplifiers include a dedicated KU210 preset that handles the suggested 150 Hz low-pass crossover and aligns the subwoofer with compact mid-high satellites such as Vyper, Lyzard, and KZ14 — the standard recipe for low-profile commercial systems with full-range response. Wall, pole, and truss mounting are supported via the K-WALL2, K-PMOUNT, and K-KCLAMP accessory families. For more output, step up to the Rumble KU212; for smaller rooms, the Rumble KU26.

Key Features

• Ultra-Slim 150 mm Cabinet Depth — The 500 x 282 x 150 mm enclosure mounts on walls, under furniture, or recessed in-wall where conventional subwoofers cannot be placed.
• 10-Inch Long-Excursion Woofer with 10-Inch Passive Radiator — The sealed radiator-loaded design produces deep, controlled bass from 40 Hz without port noise or ingress paths for dust and moisture.
• 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 lets integrators run up to four units per 4-ohm amplifier channel for efficient multi-room deployment.
• IP54 Weather Resistance — The stainless steel enclosure is rated for outdoor installation, with marine treatment available for coastal projects.
• In-Wall Flush-Mount Option — The K-WF210 accessory recesses the KU210 fully into a wall for invisible low-frequency reinforcement.
• Matched Kommander Amplifier Presets — Dedicated DSP presets align the KU210 with Vyper, Lyzard, KZ14, and other K-Array mid-high speakers.
• 4-Pin Euroblock Connectivity — The phoenix-style connector supports clean loop-through wiring in fixed commercial installations.

Typical Applications

• Conference rooms and boardrooms requiring discreet program bass
• Training rooms and multi-purpose rooms with full-range presentation audio
• Houses of worship needing concealed low-frequency support
• Commercial meeting spaces and all-hands rooms with design constraints
• Government spaces with strict placement and durability requirements
• Broadcast studios needing accurate low-end in shallow wall zones

Frequently Asked Questions

Which amplifier should drive the Rumble KU210?

The KU210 is passive and needs external amplification with a low-pass crossover at approximately 150 Hz. K-Array Kommander amplifiers are recommended because their dedicated KU210 preset manages crossover, EQ, and alignment against K-Array mid-high satellites automatically.

Which K-Array satellite speakers pair with the KU210?

Kommander presets match the KU210 to compact mid-high elements such as Vyper line arrays, Lyzard micro speakers, and KZ14 point sources, forming a full-range, low-profile commercial system. Browse companion models in the K-Array collection.

Can the KU210 be recessed into a wall?

Yes. The K-WF210 accessory (available in black, white, and custom RAL) flush-mounts the KU210 into a wall cavity for fully concealed low-frequency reinforcement in boardrooms and architectural spaces.

How many KU210 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 in distributed conference and meeting room systems.

Is the KU210 suitable for outdoor installation?

Yes. The stainless steel enclosure carries an IP54 rating for weather resistance, and a marine version with enhanced anti-corrosion treatment plus the K-KUIP protective cover is available for exposed or coastal sites.

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.
