SUBWOOFER
Rumble-KU212

The Rumble-KU212 is a compact, large-format passive subwoofer designed to deliver deep and powerful low-frequency reinforcement in professional audio systems, distributed audio systems, and installation-driven environments where high output and discreet design must coexist seamlessly.

Crafted from stainless steel, the Rumble-KU212 combines robustness, elegance, and a slim architectural profile. It is ideal for install subwoofer applications in retail sound systems, hospitality venues, cultural spaces, and outdoor sound systems. The enclosure houses a 12" neodymium magnet woofer paired with a 12" passive radiator, delivering extended bass performance with a 35 Hz – 150 Hz (-6 dB) frequency response and up to 130 dB peak SPL, all within a compact footprint suitable for space-conscious installations and underseat subwoofer applications.

With 4 Ω / 16 Ω selectable impedance and a 4-pin Euroblock connector, the KU212 integrates easily into professional powered subwoofer systems driven by K-array amplifiers. Dedicated presets ensure optimal performance, making it a reliable solution for multi-zone sound systems, high-performance installations, and design-focused audio projects.

For full-range performance, the Rumble-KU212 pairs perfectly with K-array compact mid-high loudspeakers, forming a powerful and balanced audio solution for demanding professional environments.
