QSC K12 Powered Speaker

Call for Availability

Take a look at QSC's K12 powered PA speaker. Then take a listen. You won't believe such a compact speaker can put out so much clean volume! How does QSC do it? First, they pack an astounding (and astonishingly lightweight) 1,000-watt Class D power amp into the K12. Second, they build this 12" speaker to handle all that power and give you clear, full sound at any volume. This speaker is made to give you maximum efficiency and reliability, without adding the kind of weight you'd expect such a powerful unit to have. Your live rig just got a lot lighter, a lot more streamlined, and a lot better sounding!

When you plug into the K12, you're in for the kind of performance you'd expect from a much bigger, heavier, and pricier speaker. But QSC didn't merely make a loud speaker. They made a great-sounding 1,000-watt speaker you can rely on, and they built it right. From the sound-maximizing onboard DSP and protection circuitry to built-in EQ settings, the K12 comes packed with amazing features you'll love. Plus, it accepts both XLR and 1/4" connections and even includes a set of RCA inputs for music players and line-level mixers. Get this speaker and you're ready for anything! From the moment we first heard this amazing speaker, we were blown away by its winning combo of big-time power and crystal-clear sound. You will be too!
