SUBWOOFER
Rumble-KU315

The Rumble-KU315 is a large-format passive subwoofer engineered to deliver exceptionally powerful and extended low-frequency performance in professional audio systems, outdoor installations, and high-output environments where impact, reliability, and control are essential.

Built from polyurea-coated birch plywood, the Rumble-KU315 combines structural strength, durability, and a slim line-array-inspired form factor. It is ideal for professional subwoofer applications in large venues, outdoor sound systems, fixed installations, and underseat subwoofer configurations where deep bass must integrate seamlessly into the overall system design. The enclosure houses a 15" neodymium magnet woofer paired with two 15" passive radiators, delivering a 35 Hz – 150 Hz (-6 dB) frequency response and an impressive 138 dB peak SPL, ensuring tight, high-impact low frequencies even at extreme output levels.

With a 4 Ω nominal impedance and SpeakON NL4 connectivity, the KU315 integrates easily into high-power professional audio systems. Dedicated presets, loaded on board K-array amplifiers, guarantee optimal performance and system protection, making the KU315 a reliable foundation for large-scale sound reinforcement and installation-driven projects.

Rated IP65, the Rumble-KU315 is suitable for outdoor subwoofer applications and environments exposed to dust and water, while its robust construction ensures long-term reliability in demanding conditions.
