QSC K8 Top Box Speaker

The QSC K8 features include:  

  • 8” Woofer; 1.75” diaphragm compression driver
  • 105° Nominal coverage angle
  • Maximum SPL 127 dB peak
  • 1000 watt continuous Class D power modules in all models
  • 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.
  • Attractive and professional appearance
  • Rugged ABS enclosures
  • 16 Gauge powder coated steel grille
  • Comfortable ergonomic handles
  • 35 mm pole sockets with Tilt-Direct
  • M10 rigging points
  • Eye-bold and Yoke Mount accessories available
