The Rumble-KU210 is an ultra-thin, high-performance passive subwooferdesigned to be the perfect companion to the K-array mid-high speaker for AV applications. A combination of extended frequency response with prodigious output and a virtually invisible profile make the KU210 an ideal solution even for the most ambitious projects.
The subwoofer is comprised of a 10” neodymium transducer, combined with a 10” passive transducer, instead of a reflex, which ensures that the device remains completely sealed, making it impenetrable by foreign objects such as dust, sand or water.
It is made entirely of steel, making it extremely resistant, even when deployed outside in tough weather conditions. This makes it ideal for outdoor installations where ordinary bass speakers would corrode. KU210 is also available in marine version, with special treatment to withstand marine environments and resist wear and tear and weathering.

The unit is engineered for maximum linear excursion and minimum residual noise. Its neodymium transducer has a double voice coil for two selectable impedance settings (4-16 Ω ), allowing you to combine up to 4 units powered by the same amplifier channel at 4Ω.  By recalling the dedicated presets, the K-ARRAY Kommander amplifiers are the best electronics to run any Rumble subwoofer, capable to balance perfectly all the settings you need to match with any mid-high speaker of the K-ARRAY’s catalog. This helps integrators to find their complete audio solutions in the same range of products.

Measuring 50 x 28.2 x 15.1 cm (19.7 x 11.1 x 5.9 in) and weighing 11 Kg, the KU210 is available in an elegant black or subtle white and can be customized in any RAL color as well as in premium finishes like brushed or polished steel, or with 24 K gold, rose gold, or antique gold plating, making it easy to blend in or grab attention – depending on your aim – in a variety of spaces.
