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 S8.4, 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 setups or 5.1 surround environment will optimize your mixing and listening experience.

The S8.4 utilizes a 109W Class-D amplifier to power the 8" glass-aramid composite woofer, which offers a 35 to 133 Hz frequency response with a peak SPL of 112.8 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 match your existing monitors easily. The S8.4 can be paired with any full-range studio monitor, but it really shines when paired with KRK's Rokit and VXT monitors. The curved design with a front-firing bass port provides placement flexibility. Other notable features include polarity and input sensitivity controls and a ground lift to prevent ground loops.
