Powered Studio Subwoofer The S10.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy and performance. The custom-voiced, glass-aramid woofer delivers tight, defined bass, while the Class-D power amplifier dramatically increases transient response, control and punch. The four-position selectable crossover makes it easy to adjust the subwoofer setting to your existing monitors. Pairing the S10.4 with KRK or another studio monitors delivers an optimized listening and mixing experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. KRK's S10.4 subwoofer doesn’t just deliver precise bass and a rich feature set: it’s the next dimension in subwoofer performance. 10" glass aramid composite woofer Bass extension to 27Hz with a max SPL of 117.2 dB Footswitch control enables/disables sub and crossover filter (footswitch not included) Redesigned cabinet with a lower profile and front-firing bass port Powerful, lightweight Class D amplification Optimized four-position crossover control Universal connectivity: XLR, 1/4" TRS, and RCA inputs and outputs Polarity and input sensitivity controls Ground lift switch prevents ground loops Specifications Configuration: Front Loaded, Vented Subwoofer System Type: Active Subwoofer Low-Frequency: 10" Glass Aramid Composite Woofer Frequency Response: 30Hz - 110Hz Max Peak SPL: 117.2 dB Amplifier: Class D Power Output (Continuous): 160 Watts @ 1% THD+N @ 44Hz Signal to Noise Ratio: 92 dB Amplifier Distortion (THD + N): ≤ 0.12% @-3dB Of Max Power Output 31Hz-110Hz Input Impedance: 9.4 KΩ Balanced, 9.2 KΩ Unbalanced Ground Lift: On/Off HPF Bypass: With Footswitch Only Footswitch: Optional Indicators: Power/Standby Input Connectors: XLR L/R, 1/4" TRS L/R, RCA L/R, 1/4" Footswitch LFE Input: N/A Output Connectors: XLR L/R, 1/4" TRS L/R, RCA L/R AC Power Input: 100VAC-240VAC Enclosure: 15 mm and 18 mm Reinforced MDF Finish: Black Vinyl Wrap, Baffle - Black Paint Hardware: EVA Isolation Pad Dimensions (H x W x D): (H x W x D): 13.4375" (341 mm) x 18.875" (479 mm) x 12.1875" (310 mm) Weight: 35 lb.
