K-array Thunder-KSCARDIO412P

Cardioid subwoofer with controlled bass In situations where solid low is needed, but you want to keep the rear end as quiet as possible, the Thunder-KSCARDIO412P offers a practical and effective solution. This 4×12″ cardioid subwoofer combines high output with controlled dispersion, reducing your unwanted energy on stage or against walls.

Focused layer without complex setup

With three 12″ woofers at the front and one at the rear, this subwoofer creates a natural cardioid pattern. The bass is directed forward, while the rear is suppressed by up to 20 dB. This keeps the sound tighter, clearer and more manageable – in clubs and halls as well as in churches and mobile systems.

Engineered for consistent performance

The subwoofer peaks at 138 dB SPL and goes down to 35 Hz. In Mono-Amp mode, everything works through internal filtering. Those who want more control can use Bi-Amp mode for even more precise tuning. Both modes are easy to use, making the subwoofer quick and predictable to fit in.

Sturdy housing, flexible placement

The cabinet is made of polyurea-coated birch plywood and is designed for daily professional use. The Thunder-KSCARDIO412P can be placed horizontally, vertically or side-by-side, which is useful for larger systems or limited space. The SpeakOn connectors make integration into existing installations easy.
