The 8S2 powered studio subwoofer builds upon KRKs legacy for sonic accuracy in a compact form factor. The custom-voiced, glass-aramid woofer delivers tight, defined bass, while the Class-D powered Amplifier dramatically increases transient response, control and punch, allowing you to properly engineer the low-frequency portion of the mix. The four-position selectable crossover lets you adjust the subwoofer setting easily to your existing monitors. Pairing the 8S2 subwoofer with KRK or another studio monitor delivers an optimized mixing and listening experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors if needed, without switching off the subwoofer.KRKs 8S2 subwoofer doesnt just deliver precise bass and a rich feature set: its the next dimension in subwoofer performance.Features:8" glass aramid composite wooferBass extension to 30Hz with a max SPL of 112 dBFootswitch control enables/disables sub and crossover filter (footswitch not included)Curved design with front-firing bass port for placement flexibilityPowerful, lightweight Class D amplificationOptimized four-position crossover controlUniversal connectivity: XLR, 1/4 TRS, and RCA inputs and outputsPolarity and input sensitivity controlsAll-steel grill and 15 mm reinforced MDF enclosure provide maximum strength and protectionGround lift switch prevents ground loops
