QSC K Series Loudspeakers take DJ Mixwell to an “Entirely Different Level”

January 2010 – Anaheim, CA – QSC Audio's (NAMM booth 6750) new K Series Loudspeakers have redefined the standard in compact, lightweight, high-performance powered loudspeakers, much to the delight of professional mobile Disc Jockeys.

When the snow and ice hit hard in Detroit, Nick "DJ Mixwell" Maxwell's business picks up. Why? His main audience, University of Michigan students, flock into local clubs to enjoy the vibe created by this eight-year veteran DJ. DJ Mixwell loves DJ'ing like nothing else, a fact reflected in the apparent enthusiasm of his audiences, his consistent re-bookings by club owners, and in his pursuit of audio excellence.

That pursuit is a good thing for his audiences and particularly for club owners who, DJ Mixwell admits, virtually never have in-house sound systems that come close to the standard he demands. "They're usually pretty awful," DJ Mixwell quips.

DJ Mixwell has owned three different sound systems in his career, most recently upgrading to a QSC Audio K Series Active Loudspeaker system, comprised of two K12 full-range cabinets and a single KSub. He claims the improvement over his previous active loudspeaker system was significant in increased sound quality and portability, taking his business to "an entirely different level."

The combination of a professional-looking molded ABS enclosure, uniformly matched drivers, advanced DSP, and QSC's legendary touring spec amplification has resulted in an unprecedented package. K Series is demonstrably able to outperform other molded enclosure systems due in part to one fundamental principle: the same 1,000-watt Class D amplifier module powers all four models - whether the K8, K10, K12 or KSub (dual-12" subwoofer).

"I used my previous system for a year and a half and the sound coming from the tops got to be really irritating, especially the high end." On the low end, DJ Mixwell found the frequencies around 200-400Hz were lacking and the weight and cumbersomeness of the sub boxes, quite literally, a pain. "I pulled back muscles moving those beasts more times than I care to remember," he admits with a good-natured laugh, "possibly to the financial benefit of my chiropractor."

Though DJ Mixwell finds the QSC K12 loudspeakers "far superior" in sound to his previous two sound systems, he reserves his biggest praise for his single QSC KSub. "The KSub is just on an entirely different level than anything out there," DJ Mixwell states emphatically. "They just hit so much harder in a way you can feel and they sound better than the much bigger 18-inch-loaded boxes I was using."

DJ Mixwell adds, "Especially in that the 200 to 400 Hz range, the KSubs deliver a much fuller sound to my ears."

But isn't the relative small size of a single K-Sub a problem in terms of audiences and club owners "seeing with their ears?"

DJ Mixwell answers, "A few customers have commented they're blown away by how much sound is coming from the new speakers," but the opinions he most notices are about sound quality.

"The first weekend I used the K Series in the club, I got a lot of comments that the audience enjoyed the sound a lot more," says Maxwell," concluding "that didn't surprise me; K Series has made a big improvement to my sound."
