The QSC K10 10" powered loudspeaker, featuring its revolutionary 1000W power
module, delivers the high-quality amplification, HF driver, and low-frequency
driver of the K-Series speakers, offering ~90° conical coverage and 129dB peak
output, low frequencies extending to ~56Hz. The K10 offers exceptional power and
performance from an extremely compact system, and it can also be used as an
ultra low-profile, horizontal wedge or side fill.
QSC's K10 PA speaker features a 1-3/4" HF device in its 2-way enclosure. The primary differentiator in K-series speakers 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.
