QSC KW122 – 12-Inch 1000W Active Loudspeaker / Stage Monitor

Product Overview

The QSC KW122 is a professional 12-inch, 1000W active two-way PA loudspeaker that doubles as a stage monitor. Built around a lightweight, rugged birch cabinet, it delivers crisp, natural audio for music and speech in live sound, houses of worship, and commercial AV applications.

A 12-inch woofer and 1.75-inch compression driver with Directivity Matched Transition provide even coverage, while onboard DSP and a 3-channel mixer simplify setup.

Product Description

The KW122 houses a 12-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, and the cabinet can be used upright or as a floor monitor.

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 15-inch two-way, see the QSC KW152; for a three-way model, the QSC KW153.
