High Quality Equipment

The QSC K Series is quite simply the new standard in lightweight powered loudspeaker systems. Under the direction of Pat Quilter, QSC’s team of amplifier engineers have created a new standard in Class D power modules unparalleled in the industry. Next, breaking from the traditional loudspeaker paradigm, all full-range models (K8, K10, K12) are fitted with the identical 1.75″ high-frequency (HF) device for unparalleled performance, regardless of speaker size.  Extensive digital signal processing (DSP) is employed throughout, providing levels of sonic clarity and total output that defy the system’s size and weight. Premium-grade materials, advanced construction processes and multiple mounting and suspension options allow for a wide range of live and installed applications.

Directivity Matched Transition (DMT™) 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, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.
