K-Array Rumble KU44W-2 – Ultra-Slim 2-Ohm White Passive Subwoofer

Product Overview

The K-Array Rumble KU44W-2 is the white, 2-ohm version of K-Array's ultra-slim stainless steel passive subwoofer, serving as the low-frequency element of the white Azimut KAMUT2LW compact sound system driven by the Kommander KA02 amplifier. This white installation subwoofer houses two 4-inch neodymium woofers and two 4-inch passive radiators in a sealed steel cabinet only about 4 inches deep, producing 116 dB peak SPL with response down to 45 Hz. It anchors discreet commercial audio systems in light-finished boardrooms, meeting rooms, and architectural interiors. The same 2-ohm cabinet is offered in black as the Rumble KU44-2.

Product Description

The KU44W-2 exists for one clear purpose: completing all-white K-Array system builds without compromise. In the Azimut KAMUT2LW II system, it pairs with two white KZ14W satellites, a KA02 amplifier, and a remote controller, its 2-ohm wiring letting the compact amplifier deliver full subwoofer output from a single channel. Acoustics match the entire KU44 platform: long-excursion 4-inch drivers tuned for maximum linear excursion and minimum residual noise, passive radiators instead of a port, and a fully sealed stainless steel enclosure rated IP54 against dust and moisture. A dedicated K-Array amplifier preset manages the 150 Hz low-pass crossover, EQ, and limiting. White mounting hardware — K-WALL2W and K-WALL2LW brackets, the K-PMOUNTW pole adapter, and the K-WF44W in-wall flush-mount kit — keeps the complete installation color-matched against painted walls and bright ceilings. Designers building standalone or distributed systems rather than Azimut packages should specify the 8/32-ohm Rumble KU44W I instead.

Key Features

• White Finish for Light Interiors — The factory white stainless steel enclosure disappears against painted walls, light stone, and bright ceiling lines.
• 2-Ohm Configuration for Azimut Systems — Purpose-wired for the KAMUT2LW system's Kommander KA02 amplifier to deliver full output from one compact channel.
• Ultra-Slim 500 x 116 x 101 mm Profile — The roughly 4-inch-deep cabinet mounts along walls, under counters, and behind millwork.
• Dual 4-Inch Woofers with Dual Passive Radiators — Neodymium drivers extend bass response to 45 Hz with maximum linear excursion and minimum residual noise.
• 116 dB Peak SPL Output — Output capability anchors foreground music and speech systems in small to mid-size rooms.
• Sealed Stainless Steel IP54 Construction — The weather-resistant enclosure suits indoor and protected outdoor placement.
• Dedicated Amplifier Preset — K-Array amplifiers apply factory crossover, EQ, and limiter settings automatically.
• Color-Matched Mounting Hardware — White wall brackets, pole adapter, and in-wall flush-mount kit complete a fully white installation.

Typical Applications

• Boardrooms and conference rooms with white Azimut KAMUT2LW systems
• Commercial meeting spaces with light architectural finishes
• Houses of worship integrating bass into white walls and columns
• Multi-purpose rooms and training rooms with design-led installed audio
• Government spaces where equipment must remain visually discreet

Technical Specifications

Frequently Asked Questions

What system is the KU44W-2 designed for?

It is the bass element of the white Azimut KAMUT2LW II system, paired with two KZ14W satellites and a Kommander KA02 amplifier. It is also sold individually for replacements and custom white system builds.

Why 2-ohm impedance instead of 8/32?

The 2-ohm wiring lets the compact KA02 amplifier in the Azimut system drive the subwoofer to full output on a single channel. For distributed designs that parallel multiple subwoofers per channel, choose the 8/32-ohm KU44W I.

Is the KU44W-2 acoustically identical to the black KU44-2?

Yes. Drivers, enclosure, impedance, and performance match the black KU44-2; only the finish differs.

Are white mounting accessories available?

Yes. K-Array offers white wall brackets (K-WALL2W, K-WALL2LW), a white pole mount (K-PMOUNTW), and a white in-wall flush-mount kit (K-WF44W) for fully color-matched installations.

Can the KU44W-2 be installed outdoors?

The sealed stainless steel enclosure carries an IP54 rating, suitable for protected outdoor placement; consult Creation Networks for fully exposed or marine environments.

What warranty applies?

K-Array products carry a 5-year manufacturer warranty, supported by Creation Networks as an authorized dealer. Browse the full line in the K-Array collection.
