K-array has released the Thunder-KScardio412P passive cardioid subwoofer, a single-cabinet design offering precise low-frequency control without the complexity associated with cardioid subwoofer systems.
‘Cardioid subwoofer configurations have long been valued for their ability to reduce unwanted rear sound radiation. This offers a significant advantage in live event and fixed installation environments where stage spill and monitor feedback can compromise audio quality,’ the company states. ‘Achieving this has traditionally required carefully configured multi-cabinet arraying, external DSP processing, and the application of delays. The Thunder-KScardio412P is designed to take away that complexity, delivering true plug-and-play cardioid performance from a single enclosure with no additional signal processing or time alignment required in standard configurations.’
The cabinet is loaded with four 12-inch neodymium magnet woofers, providing low-frequency response down to 35Hz and a maximum output of 138dB SPL. The KScardio412P weighs 61.7kg, a compact footprint for the power on offer, making it practical for both touring rigs and permanent installs. The enclosure is constructed from birch plywood with a polyurea coating, built to withstand intensive use and regular transport, and is available in black or custom RAL finishes.
The KScardio412P supports both mono-amp and bi-amp operating modes, offering flexibility for engineers working with different amplifier configurations. In bi-amp mode, rear attenuation of up to 20dB is achievable, allowing highly controlled low-frequency directivity. Critically, the cardioid pattern remains stable whether the cabinet is deployed horizontally or vertically, and in single or side-by-side configurations. This addresses an important practical consideration for system designers working across varied venue layouts.
The sub is suited to a wide range of applications, including live touring, theatres, clubs, DJ venues, beach bars, rooftops and broadcast environments. It is compatible with K-array’s K-Framework3 software for system design and configuration.
‘The KScardio412P is a single cabinet that delivers powerful, predictable low-end with genuine rear rejection, straight out of the box,’ says K-array Brand Manager, Lorenzo De Poi. ‘The response we received at ISE confirmed that this is the kind of solution the market has been asking for, and we’re delighted to be putting it into the hands of A/V professionals worldwide.’
The Thunder-KScardio412P joins K-array’s Thunder subwoofer range and is available now through K-array’s global distribution network.
