Thunder / K-array Italy
The K-array Thunder-KS2 I is a compact active subwoofer built around an 18” driver and a commanding 4×1500W @ 4Ω Class-D amplifier with onboard DSP, designed to anchor K-array sound reinforcement while powering compatible passive loudspeakers from its integrated outputs.
Conceived as a system hub, the KS2 I combines advanced DSP (grouping, fully parametric EQ, limiters, flexible routing, and up to 230 ms delay) with wireless control via K-array Connect and scalable management through K-framework3. Its osKar embedded platform runs on an internal quad-core processor, while a symmetric-ported bass-reflex design and polyurea-coated Finnish birch plywood cabinet ensure touring-grade durability—finished in black/white or full RAL for seamless integration.

Simply combining two or more subwoofers to obtain a configuration that guarantees cardioid diffusion even throughout the low frequencies promises to give you a cleaner sound on stage, minimise risk of acoustic feedback, and in general a greater control over sound design the way you want it.

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.
