The QSC K8 is one of the best 8” powered PA speakers on the market. The K8 loudspeaker features XLR and 1/4” TRS mic/line level inputs. QSC K series speakers offer a fly-mount optional feature.

QSC's K8 is a lightweight powered loudspeaker that features a 1000 Class D power module and is fitted with an identical woofer and a 1.75" HF transducer.  The K8 also features auto-standby mode, XLR & 1/4" TRS mic/line level ins, RCA phono ins, direct outs on each channel, a balanced out for daisy-chaining up to three sources and extensive DSP processing.  EQ settings for both the high-freq. and low-freq. transducers are adjustable on each unit.  LEDs can be set to show when the unit is on or when its clip limiter has been engaged.  The extended bass LF setting allows for integration of an external subwoofer into the sound system.

Features fly-mount options as well as the Tilt-Direct™ pole cup mounting system for a 7.5° downward tilt for better sound coverage.  Multiple units can be daisy-chained for total gain control from a single remote pot.  Also features a steel grille and is housed in an ABS enclosure.

QSC K8 Features:

  • 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 1/4” 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
  • Eyebolt and yoke mount accessories available (soldseparately)
