Description

The KRK Systems S12.4 12″ Powered Studio Subwoofer is engineered to deliver deep, precise low-frequency reproduction for professional mixing and production environments. Designed to complement KRK and other studio monitors, the S12.4 extends your system’s low-end response while maintaining tight, controlled bass performance.

At the core of the S12.4 is a 12” Kevlar® aramid composite woofer that produces ultra-tight and defined bass with excellent transient response. Powered by a Class D amplifier, the subwoofer delivers strong output with improved efficiency, control and punch — making it ideal for stereo, surround, broadcast and production applications.

The four-position selectable crossover allows seamless integration with your existing monitors. The optional footswitch-controlled bypass function lets you instantly mute the subwoofer and send full-range audio to your monitors for accurate A/B comparison during mixing sessions.

Built with a reinforced MDF enclosure and optimized front-firing port design, the S12.4 minimizes port turbulence while enhancing low-frequency extension and reducing boundary coupling. With professional connectivity and durable construction, the S12.4 provides powerful and accurate bass performance for demanding studio workflows.
