The KRK Systems S12.4 12″ Powered Studio Subwoofer<\/strong> 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\u2019s low-end response while maintaining tight, controlled bass performance.<\/p>\n

At the core of the S12.4 is a 12\u201d Kevlar\u00ae aramid composite woofer<\/strong> that produces ultra-tight and defined bass with excellent transient response. Powered by a Class D amplifier<\/strong>, the subwoofer delivers strong output with improved efficiency, control and punch \u2014 making it ideal for stereo, surround, broadcast and production applications.<\/p>\n

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.<\/p>\n

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.<\/p>\n
