Thunder / K-array Italy
K-array Thunder KS1 I
The K-array Thunder-KS1 I is a compact active subwoofer that pairs a 12” neodymium driver with a formidable 4×1500W @ 4Ω Class-D amplifier and onboard DSP, powering both deep low-end and select K-array passive loudspeakers from one elegant core.
Design Story
Designed as the “brains and brawn” of a K-array reinforcement rig, the KS1 I combines flexible DSP—grouping, fully parametric EQ, limiters, routing, and up to 230 ms delay—with intuitive control via K-array Connect and K-framework3 for fast system tuning at scale. Its symmetric-ported bass-reflex design and rugged Finnish birch plywood cabinet with polyurea coating are built to stay dependable in demanding environments, while black/white or full RAL finishing keeps the installation visually refined.
Giving You Ultimate Sound Control

Crafted for Heavy Touring
The Thunder Series subs are built with a choice of Finnish birch plywood so it lightweight and incredibly resistant, making it the perfect speaker for audio rentals.The new polyurea paint and the cataphoresis treatment for the front grill, further treated with powder coating, also give greater resistance to the harsh weather environments often experienced on the road.
Adaptable Even Off The Stage
