The K12 is the top contender in the K Series range of powered PA speakers - it sounds fat. Big, solid bass frequencies, punchy mids and sweet highs. These speakers are great for a pumping house party, mid sized clubs and function. The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. Under the direction of Pat Quilter, QSC's team of amplifier engineers have created a new standard in Class D power modules unparalleled in the industry. Next, breaking from the traditional loudspeaker paradigm, every model is fitted with the identical 1.75" HF device (full-range models) and woofers of the same high quality for unparalleled performance, regardless of speaker size.
