Introduction
The Thunder–KS3 I is a compact active subwoofer featuring a 21” cone driver and a powerful 4x 2500W @ 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 midrange 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 an user friendly interface for remote control of the DSP main parameters and easy configuration of the signal routing.
