The Rumble-KU212 is an ultra-thin, high-power passive subwoofer designed as the perfect companion to the K-array’s mid-high speakers. A combination of extended frequency response with prodigious output and a discreet form factor make the KU212 an ideal solution for complex medium and large-format projects like bars, lounges, home cinemas, and small clubs. One of the largest subwoofers of the K-array’s Rumble line, it is comprised of a 12” neodymium transducer combined with a 12” passive transducer that makes it impenetrable by foreign objects such as dust, sand or water, which over time can ruin a speaker. The KU212 is made entirely up of steel, making it extremely resistant, even when deployed outside in tough weather conditions. All these properties make it ideal for aquatic environments where ordinary bass speakers would get damaged in a short time. On request, the Marine version features even higher treatments against salt corrosion.
KU212’s 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 preset, 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 wide range of products.
Measuring 65,0 cm x 33,0 cm x 20,0 cm (25.8“ x 13.0” x 7.9“) and weighing 18kg, the KU212 is c, making it easy to blend in or grab attention - depending on your aim - in a variety of spaces.
