K8The QSC K8 8" powered loudspeaker features a 1000-watt Class-D power module, and its extremely compact size won't intrude on audience sightlines. Its 105 wide dispersion is a major advantage when the audience is up close to the loudspeaker. Low frequencies extend to 61Hz (-10dB) and the unit outputs an amazing 127dB.QSC's K8 speaker features a 1-3/4" HF device in its 2-way enclosure. The primary differentiator is the resulting output dispersion-the K8 being the widest at 105 and the K12 the narrowest at 75. This radical approach is achievable due to a process called Directivity Matched Transition (DMT). DMT allows QSC to take advantage of a fundamental law of acoustics: smaller diameter woofers have wider coverage patterns than larger ones. The K Series matches the HF device to the LF dispersion, allowing for the smoothest and flattest frequency response possible across the entire sound field.Add to this advanced DSP processing and an enclosure molded from ABS-a material far more rugged and sonically pleasing than conventional plastics-and the QSC K8 Speaker delivers exceptional performance in this category of loudspeakers.Several proprietary QSC DSP technologies are incorporated into the K8 PA speaker. One such technology is Digital Extension and Excursion Processing (DEEP). DEEP allows the K8 to deliver levels of low-frequency extension previously impossible in enclosures of this size. Intrinsic Correction, first featured in QSC line-array technology, use dozens of spatially averaged measurements mapped to the processor to deliver smooth and accurate reproduction across the entire sound field.Preventing amplifier clipping or overload is QSC's proprietary GuardRail technology. GuardRail closely monitors the input voltage and controls the amplifier output stage before the
