The KRK Systems S10.4 Powered Studio Subwoofer<\/strong> expands your monitoring system with deep, tight and controlled low-frequency performance. Designed to complement KRK studio monitors and other professional monitoring setups, the S10.4 delivers accurate bass extension for mixing, mastering, sound design and content production.<\/p>\n

At its core is a custom-voiced 10\u201d glass-aramid composite woofer<\/strong> housed in a reinforced MDF enclosure. The front-loaded, vented design with optimized front-firing port enhances low-frequency extension while minimizing port turbulence and boundary coupling. Powered by a high-efficiency Class D amplifier<\/strong>, the S10.4 provides improved transient response, control and punch for precise bass reproduction.<\/p>\n

A four-position selectable crossover allows seamless integration with your existing studio monitors, while the optional bypass footswitch control<\/strong> lets you instantly mute the subwoofer and send full-range audio to your monitors for accurate A\/B comparison during mixing sessions.<\/p>\n

With flexible connectivity including balanced XLR, TRS and RCA inputs and outputs, plus ground lift and high-pass filter bypass functionality, the S10.4 integrates easily into professional studio environments. Built for durability with reinforced MDF construction and EVA isolation pad hardware, this subwoofer delivers reliable performance for demanding production work.<\/p>\n

For producers and engineers seeking accurate low-end extension and mix confidence, the KRK S10.4 adds the next dimension of subwoofer performance to your studio.<\/p>\n
