The Rumble-KU315 is a passive subwoofer designed to deliver exceptional powerful and extended low-frequency performance in professional audio systems where impact, reliability, and control are essential.
The polyurea-coated birch plywood enclosure combines structural strength, durability, and a slim line-array-inspired form factor housing a 15" neodymium magnet woofer paired with two 15" passive radiators that deliver extended bass performance with a 35 Hz – 150 Hz (-6 dB) frequency response and up to 138 dB peak SPL. 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.
KU315 comes in standard Black or White and can be customized with any RAL color.
