The Thunder-KS1 I is a compact active subwoofer featuring a 12” cone driver and a powerful 4x 1500W @ 4Ω audio amplifier module with built-in DSP. The audio power output connectors allow the Thunder subwoofers to drive a wide range of K-array passive loudspeakers. Compatible with mid-high loudspeaker and other passive subwoofers, the self powered Thunder subwoofers with DSP are designed to be the core devices in K-array sound reinforcement systems. The dedicated K-array Connect mobile app provides a user friendly interface for remote control of the DSP main parameters and easy configuration of the signal routing.
