Rumble / K-array Italy
Rumble KU210
The K-array Rumble-KU210 is an ultra-thin passive subwoofer built for AV-grade installations, pairing a 10” neodymium driver + 10” passive radiator in a fully sealed steel enclosure with selectable 4Ω/16Ω impedance for powerful, discreet low-end indoors or outdoors.
Design Story
Instead of a reflex port, the KU210 uses a passive transducer to stay completely sealed—protecting performance from dust, sand, and water while delivering maximum linear excursion with minimal residual noise. Its all-steel (and optional Marine-treated) construction plus Kommander amplifier presets make it a rugged, precision-tuned companion for K-array mid-high systems, finished in black/white, custom RAL, or premium plated steel for architectural integration.
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.
