Audio engineers, studio musicians, and audio enthusiasts looking for a high-quality active subwoofer to extend the low frequencies of their monitor setup will be thrilled with the KRK S10.4, a fourth-generation powered studio subwoofer that delivers tight defined bass with remarkable transient performance, control, and punch. Adding this subwoofer to your 2.1 setup or 5.1 surround environment will optimize your mixing and listening experience.

The S10.4 utilizes a 160W Class-D amplifier to power the 10" glass-aramid composite woofer which offers a 33 to 130 Hz frequency response with a peak SPL of 117.2 dB. XLR, 1/4", and RCA inputs and outputs are available, allowing you total flexibility when connecting additional subs and monitors. A four-position selectable crossover lets you adjust the subwoofer settings to easily match your existing monitors. The S10.4 can be paired with any full-range studio monitor, but really shines when paired with KRK's Rokit and VXT monitors. The curved design with front-firing bass port provide placement flexibility. Other notable features include polarity and input sensitivity controls as well as a ground lift to prevent ground loops. The rugged MDF enclosure and all-steel grille ensure maximum strength and protection.
