Thunder / K-array Italy
Thunder KS4P I
The K-array Thunder-KS4P is a high-output passive subwoofer with dual 18” neodymium woofers (30 Hz–150/450 Hz via DSP crossover), delivering up to 141 dB max SPL with omnidirectional low-end authority for professional reinforcement.
Design Story
Engineered for flexible system building, the KS4P uses dual SpeakON NL4 connections to accept 2- or 4-wire feeds from amplifiers/active systems and to loop signal cleanly to additional loudspeakers. Its long-excursion dual-18 design is housed in a polyurea-coated birch plywood enclosure with IP54 protection, finished in black/white or custom RAL to suit both touring rigs and permanent installs.
Giving You Ultimate Sound Control
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.
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
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.
