The QSC KW Series is a high-output powered speaker lineup that projects commanding audio across the frequency spectrum to a wide listening area. Armed with 1000 watts of continuous Class-D amplifier power and 1.75-inch high-frequency drivers throughout the line, the KW Series is available in a 12-inch model (KW122), 15-inch model (KW152) and a 15-inch/6.5-inch 3-way model (KW153). The QSC KW Series also includes an 18-inch subwoofer as well (KW181). These wood enclosure speakers are an evolution in style - more lightweight, more resonant, and more manageable than earlier renditions of similar speakers. QSC KW Speakers feature premium materials, top-notch electronics, extensive DSP (digital signal processing), and tone controls to tailor the sound to your exact liking.
