QSC K8 2-Way Active Loud Speaker (Pair)

Description 8” Woofer; 1.75” diaphragm compression driver 105° conical DMT coverage Maximum SPL 127 dB peak Attractive and professional appearance Rugged ABS enclosures 16-gauge powder coated steel grille 1000-watt continuous Class D power modules in all models Comfortable ergonomic handles 35 mm pole sockets with Tilt-Direct™ M10 rigging points Eyebolt and yoke mount accessories available Onboard mixer with two combo XLR and ¼” inputs, and stereo RCA inputs, (three audio input sources); two direct channel outputs and single summed balanced output Extensive DSP enhances system performance: DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones. Intrinsic Correction™, first featured in our high-end line-array products maps 65–75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat band pass target. The result is a speaker that behaves equally well across the entire sound field. DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies. GuardRail™ protection protects both the amplifier module and your performance from unnatural and destructive clipping.
