The KW153 from QSC is a professional-quality active 3-way PA loudspeaker. Ideal for music and speech applications, the lightweight and rugged birch cabinet houses a 15" woofer, a 6.5" midrange driver, and a 1.75" compression tweeter to deliver crisp, natural audio with a wide frequency response. A pair of efficient Class-D amplifiers provide a combined power of 1000W for strong audio with low distortion. Directivity Matched Transition technology provides matched low and high frequency coverage across your entire listening area to eliminate "dead" and "hot" zones.
