The Thunder-KSCARDIO412P is a high-performance passive cardioid subwoofer designed to deliver powerful and controlled low-frequency reinforcement while significantly reducing rear sound radiation. Suitable for both professional live sound and fixed installations, it ensures focused bass coverage with minimal energy behind the system.
Its cardioid configuration enables effective rear attenuation, improving directivity and reducing unwanted stage spill. The system supports both mono-amp and bi-amp configurations, offering flexibility depending on the application.

Highlights
Rafted 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.
Ultimate sound control
Low frequencies have always been one of the most challenging aspects of system design. Their natural omnidirectional behavior makes control difficult, often resulting in unwanted energy on stage and a less defined sound. The combination of integrated cardioid technology and advanced simulation environments allows low-frequency behavior to be predicted and shaped with precision. This approach enables controlled directivity, reduced rear radiation, and a cleaner, more consistent acoustic experience across any application.
