QSC KW153 is a professional-quality 3-way active speaker. Ideal for music and voice applications, the lightweight and robust speaker houses a 15" woofer, a 6.5" mid-range driver, and a 1.75" compression tweeter to deliver clear and natural sound with a wide frequency response. A pair of efficient Class D amplifiers provides a combined power of 1000W for loud audio with low distortion. Directivity Matched Transition technology provides high and low frequency coverage across the entire listening area to eliminate "dead" and "hot" spots.

It offers you XLR and 1/4-inch TRS combo inputs that accept microphone and line-level input, while a set of RCA inputs (except KSub) allows for additional connectivity with portable MP3 players, CD players, and line-level mixers. Up to three audio sources can be mixed internally and summed to a balanced output for a multi-unit daisy chain connection. Separate direct outputs are also provided on each channel for additional output flexibility.
