KRK S10.4 Powered 10" Studio Monitor Subwoofer
KRK S10.4 Powered Studio Subwoofer Bring deeper, tighter and more controlled low-end to your studio monitoring system with the KRK S10.4 powered studio subwoofer. Designed for music production, mixing, mastering, sound design, broadcast and professional audio applications, the KRK S10.4 combines a 10-inch glass aramid composite woofer with a powerful 160-watt Class-D amplifier to deliver extended, accurate bass with the punch and control expected from KRK monitoring systems. With bass extension down to 27 Hz and a maximum peak SPL of 117.2 dB, the S10.4 lets you hear more of the low-frequency information in your music, including bass lines, kick drums, sub-bass, sound effects and other critical elements that can be difficult to judge accurately on smaller studio monitors. Powerful, Accurate Low-End The S10.4 features a custom-voiced 10-inch glass aramid composite woofer designed to produce tight, defined bass. Its Class-D amplification provides high output while maintaining the fast transient response and control needed for critical studio monitoring. The result is extended low-frequency performance that complements your existing studio monitors without sacrificing clarity or accuracy. Easy Integration With Studio Monitors The S10.4 is designed to work with KRK studio monitors as well as powered monitors from other manufacturers. A four-position selectable crossover makes it easy to configure the subwoofer for your monitoring system and achieve a more balanced full-range monitoring setup. Universal connectivity includes: XLR left/right inputs and outputs 1/4-inch TRS left/right inputs and outputs RCA left/right inputs and outputs 1/4-inch footswitch connection Four-position crossover control Polarity control Input sensitivity control Ground lift switch Convenient Subwoofer Bypass The S10.4 includes KRK's dedicated bypass-control system, allowing you to quickly mute the subwoofer and send full-range audio to your studio monitors when used with the optional footswitch. This makes it easy to compare your mix with and without the extended low-frequency contribution of the subwoofer—without leaving your listening position. The footswitch is optional and sold separately. Front-Firing Port & Reinforced Enclosure The S10.4 uses a front-firing bass port engineered to provide low-frequency extension while helping reduce boundary coupling and minimise port turbulence. The enclosure is constructed from reinforced MDF, with a durable black vinyl finish and EVA isolation hardware. Its redesigned lower-profile cabinet is built for demanding studio environments. Ideal for Music Production & Critical Listening The KRK S10.4 is an excellent choice when your studio monitors need additional low-frequency extension. It is suited to: Music production Mixing Mastering Recording studios Home studios Project studios Sound design Broadcast production Film and post-production Electronic music and bass-heavy production Critical listening Whether you're checking the impact of a kick drum, balancing a bass guitar, judging sub-bass in electronic music or monitoring low-frequency effects in film and sound design, the S10.4 provides the extended low end needed to make more informed mixing decisions.
