Rumble-KU210

The Rumble-KU210 is an ultra-thin, high-performance passive subwoofer designed to complement K-array mid-high speakers for AV applications. Combining an extended frequency response with high output and a virtually invisible profile, the KU210 is the ideal solution for ambitious audio installations.

Sealed & Weather-Resistant Design

Featuring a 10” neodymium transducer paired with a 10” passive radiator, the KU210 eliminates the need for a reflex system, keeping the device fully sealed. This makes it impermeable to dust, sand, and water, ensuring durability in outdoor installations. The unit is constructed entirely from stainless steel, providing exceptional resistance to corrosion, even in harsh environments. For marine applications, a specialized treatment is available on request.

Selectable Impedance & Seamless Integration

With a double voice coil, the KU210 allows selectable impedance settings of 4Ω or 16Ω. At 16Ω, up to four units can be powered by a single 4Ω amp channel. Dedicated presets for K-array Kommander amplifiers ensure optimal balance with any mid-high speaker in the K-array catalog, simplifying system integration.

Compact & Customizable

Measuring just 500 x 282 x 151 mm (19.7 x 11.1 x 5.9 in) and weighing 11 kg (24.3 lb), the KU210 is compact yet powerful. Available in black or white, it can also be customized in any RAL color or premium finishes such as brushed or polished steel, 24K gold, rose gold, and antique gold plating. Whether blending into a space or making a statement, it adapts to diverse environments.
