The QSC KS212C 3600-Watt Dual 12" Active Cardioid Subwoofer is a revolution in bass management, delivering precision low-end control in a single enclosure. Unlike traditional subwoofers that disperse sound omnidirectionally, the KS212C is engineered to focus its powerful bass output forward, effectively minimizing unwanted low-frequency build-up behind the stage. This is achieved through its innovative cardioid design, which provides a substantial 15dB SPL attenuation from front to back, ensuring the sound remains where you want it—toward the audience.

At the heart of the KS212C is a robust 3,600W Class-D amplifier, driving dual 12" long-excursion drivers housed in a dual 6th order bandpass configuration. This design offers deep, tight bass that’s as controlled as it is impactful, making it ideal for live performances, DJ setups, and installed sound systems. The subwoofer also includes advanced DSP technology for seamless integration with other speakers, optimizing phase alignment and crossover points for a perfectly balanced audio experience.

This subwoofer is not only powerful but also practical. Its durable wooden enclosure, equipped with four low-noise casters and ergonomic handles, promises both longevity and ease of transport. The inclusion of M20-threaded sockets allows for versatile pole-mounting options, making the KS212C adaptable to various setups and environments.
