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 two-way enclosures. The primary differentiator is the resulting output dispersion - the K8 being the widest at 105° and the K12 the narrowest at 75°."
This approach is achievable through 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. QSC has simply matched the HF device to the LF dispersion, allowing for the smoothest and flattest frequency response possible across the entire sound field.
