Rumble-KU315

The Rumble-KU315 is the most powerful passive subwoofer in the Rumble series, delivering a nominal rated power of 2000 W at 4 Ω. Built from water-resistant polyurea-coated birch plywood, this ultra-thin subwoofer features a 15" neodymium transducer housed in a shallow, slim design. It is also certified for marine applications, ensuring durability even in the toughest environments.

Innovative Sealed Design

Unlike conventional subwoofers, the KU315 eliminates reflex openings and instead incorporates two additional 15” passive radiators. This enhances linear transducer excursion while minimizing residual noise. Combined with an upgraded SpeakON NL4 connector, this makes the KU315 highly resistant to harsh weather conditions, making it a great choice for outdoor installations.

Optimized Power & System Integration

The K-array Kommander amplifiers are the ideal choice for powering the KU315, featuring dedicated presets that ensure perfect balance with any mid-high speaker in the K-array catalog. With an extended frequency response, impressive output, and a discreet form factor, the KU315 is ideal for medium and large-scale applications such as clubs, lounges, theaters, cinemas, and auditoriums.

Compact & Customizable

Measuring 1230 x 450 x 250 mm (48.4 x 17.7 x 9.8 in) and weighing 40 kg (88.18 lb), the KU315 is both powerful and space-efficient. Available in black or white, it can also be customized in any RAL color to seamlessly blend into any installation environment.
