Product Description

The QSC K8 Powered PA Speaker is powered by a Pat Quilter designed 1000 watt QSC Class D power module. Extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system's size and weight. Plus the K8 is housed in a rugged ABS enclosure with a professional appearance that is at home in any application. ABS is a far more robust material than conventional speaker plastics and offers an additional measure of sonic clarity due to its internal rigidity. Ergonomic aluminum handles and a highly protective steel grille complete the package for ease of transport and long term durability.

Preset Application Settings
On-board switches provide preset EQ settings. The HF setting can be set to VOCAL BOOST for additional presence in the critical mid frequency area or FLAT for accurate reproduction of the incoming signal. The LF switch can be set to NORM, DEEP for additional bass extension, or EXT SUB for use with an external subwoofer. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the unit is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation.

Extensive DSP
  • 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 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass 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, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping
Set Up
The QSC K8 features a unique Tilt-Direct pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired.

What is your overall opinion of this product?
Amazing that so much sound comes out of these tiny speakers a size of a 25 pound dumbbell. A little pricey but sometimes you get want you pay for. Well worth the investment. Plus comes with a 6 year warranty from QSC, no other powered speaker comes with that kind of warranty and quality in my opinion. The sound will amaze you!
