Rumble / K-array Italy
Rumble KU44 I
The K-array Rumble-KU44 is an ultra-compact, arrayable bass element (50–150 Hz) built with two 4” neodymium drivers + two 4” passive radiators and selectable 8Ω/32Ω impedance, delivering powerful low-end that pairs seamlessly with mid-high line arrays in a virtually invisible profile.
Design Story
Engineered for maximum linear excursion with minimal residual noise, the KU44 is designed to scale—forming bass line arrays that extend true line-array behavior down to 50 Hz when placed beside or behind Kobra arrays. Its all-steel, weather-resistant construction (with an optional Marine treatment) and dedicated mounting ecosystem make it a discreet yet durable solution for demanding permanent or portable installs.
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.
