QSC KW152 1000 Watt 15 Inch 2 Way Active Loudspeaker

Building on the success of the K Series, the KW152 represents the next evolutionary step in wood enclosure loudspeakers. QSC system engineers have created the KW152 to feature all the groundbreaking electronic attributes of the popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.

High Output 
Like the K Series models, the KW152 model features a QSC designed, 1000 Watt (2x 500) Class D power module. And continuing in the K Series tradition, every model is fitted with the identical high-output 1.75" HF device (full-range models) and woofers of the same high quality design, regardless of speaker size.

Defined Coverage Area
Directivity Matched Transition (DMT™) provides for matched LF and HF coverage across the entire listening area of the KW152, eliminating unnatural "dead" or "hot" frequency zones.

DSP
Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a product in this category:

• Intrinsic Correction™, first featured in QSC's high-end line array products maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to amaximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
• DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
• GuardRail™ protection, first introduced on QSC's GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.
