Costa Mesa, CA (April 3, 2009)--QSC Audio has released its new K Series product group--a line of compact, lightweight, high-performance powered loudspeakers.

The K series is housed in molded ABS enclosures with uniformly matched drivers, advanced DSP, and the same 1,000-watt Class D amplifier module, which powers all four models, whether the K8, K10, K12 or KSub (dual-12" subwoofer).

QSC Director of Entertainer Solutions Ray van Straten states, "The K Series has been designed entirely without compromise, from the ground up. QSC has departed from convention and at the same time exploded a myth that smaller woofers must equate to lower performance. Competitors will typically use the highest power amplifier and the best quality drivers in the largest format model, while designing their smaller format models with lower power amplification and lesser performing components. This allows them to reduce the price of the smaller models, further propagating the myth that a smaller woofer enclosure necessitates lower performance."

He continues, "Apart from using the same amp module across the line, we are also using the same quality woofer motor in all four models, and the same 1.75" HF device in the three 2-way enclosures. The primary differentiator is the resulting output dispersion--the K8 being the widest at 105° and the K12 the narrowest at 75°. The choice for the customer then is not 'good, better, best', but 'best, best, best'--and 'How wide a box do I need?'"

Since ssmaller diameter woofers have wider coverage patterns than larger ones, QSC has matched the HF device to the LF dispersion in an effort to provide smooth, flat frequency response across the entire sound field.

Several proprietary QSC DSP technologies are incorporated into the K Series, such as DEE, which is said to provide low-frequency extension, and Intrinsic Correction, which utilizes dozens of spatially-averaged measurements, mapped to the processor in an effort to provide deliver smooth and accurate reproduction across the sound field.

Preventing amplifier clipping or overload is QSC's proprietary GuardRail technology, also present in its popular GX amplifier line. GuardRail monitors the input voltage and controls the amplifier output stage before the onset of clipping.

The K Series will be shipping nationwide in mid-May.
