QSC KW152 – 15-Inch 1000W Active 2-Way Loudspeaker

Product Overview

The QSC KW152 is a professional 15-inch, 1000W active two-way PA loudspeaker for music and speech reinforcement. A lightweight, rugged birch cabinet houses a 15-inch woofer and a 1.75-inch compression tweeter for crisp, natural audio across a wide frequency range.

Dual Class-D amplification, Directivity Matched Transition coverage, onboard DSP, and a 3-channel mixer make it a versatile main loudspeaker for live and install use.

Product Description

The KW152 houses a 15-inch woofer and a 1.75-inch compression tweeter driven by a pair of efficient Class-D amplifiers with a combined 1000W output for strong, low-distortion sound. Directivity Matched Transition (DMT) matches low- and high-frequency coverage across the listening area to eliminate dead and hot zones.

Connectivity includes XLR-1/4-inch combo inputs and line-level RCA inputs, with up to three sources mixed internally and sent to the outputs. Direct XLR outputs are provided per channel plus a mix output for daisy-chaining. Extensive internal DSP includes Intrinsic Correction, DEEP, and GuardRail for sonic clarity and component protection.

The rugged birch enclosure is built for portable and install use. For a 12-inch model, see the QSC KW122; for a three-way 15-inch, the QSC KW153.
