Rumble / K-array Italy
Rumble KU212
The K-array Rumble-KU212 is an ultra-thin, high-power passive subwoofer featuring a 12” neodymium driver + 12” passive transducer in a sealed steel enclosure with selectable 4Ω/16Ω impedance, delivering prodigious low-end for medium-to-large projects—from lounges and clubs to home cinemas—indoors or outdoors.
Design Story
As the largest Rumble model, the KU212 replaces a reflex port with a passive transducer to stay fully sealed, protecting performance from dust, sand, and water while maintaining maximum linear excursion and low residual noise. Its all-steel build (with optional Marine treatment) is made for harsh environments, and Kommander amplifier presets plus black/white, custom RAL, or premium plated finishes make it easy to tune and visually integrate.
Extremely compact subwoofers
Ultra-compact, yet powerful bass systems engineered for maximum linear excursion and minimum residual noise that boast extended low-frequency response. The use of passive radiators, rather than having reflex openings, makes any Rumble subwoofer completely sealed off from foreign objects and particularly suitable for outdoor applications.
Premium Finishes
Similar to high-end fashion accessories and jewelry, our products undergo the most advanced coating process for a more beautiful and lustrous look.
Color Customizable
We have the ability to customize your project by color matching your system to any RAL code to help you to better integrate the speakers into a wide variety of venues.
