10” Glass-Aramid Composite Woofer: The KRK S10.4 Powered Studio Subwoofer features a custom-voiced 10” glass-aramid composite woofer, providing precise, punchy, and well-defined bass. This ensures that low-end frequencies are reproduced with clarity and accuracy, making it ideal for critical audio tasks like mixing, mastering, and sound design.

Class-D Amplifier: The built-in Class-D power amplifier delivers 160 watts of continuous power, enhancing the subwoofer’s control, punch, and transient response. The amplifier’s efficiency ensures clean, undistorted bass while maintaining low heat generation, which is perfect for long studio sessions.

Four-Position Selectable Crossover: The S10.4 is equipped with a versatile four-position selectable crossover, allowing seamless integration with studio monitors. This feature lets you adjust the frequency response to match the specific needs of your studio setup, ensuring a balanced, well-coordinated sound experience.

Bypass-Control Feature: The exclusive bypass-control feature allows you to switch between full-range audio and subwoofer modes effortlessly. This is especially useful during mixing, as it lets you quickly reference how your mix sounds with and without the subwoofer. The bypass control can be activated via an optional footswitch for hands-free operation.

Robust MDF Enclosure with Front-Firing Port: Constructed from heavy-duty reinforced MDF, the S10.4 is built for durability. Its front-firing port design extends low frequencies while minimizing turbulence and boundary coupling. This results in cleaner, distortion-free bass, even at high volumes.

Ultra-Low Frequency Response: The S10.4 extends bass frequencies down to 27Hz, making it ideal for genres and audio projects that demand powerful, deep bass reproduction. This subwoofer can achieve a maximum SPL of 117.2 dB, ensuring that it delivers both volume and clarity in any studio environment.
