QSC KW153 – 15-Inch 1000W Active 3-Way Loudspeaker

Product Overview

The QSC KW153 is a professional 15-inch, 1000W active three-way PA loudspeaker for music and speech reinforcement. A lightweight, rugged birch cabinet houses a 15-inch woofer, a 6.5-inch midrange driver, and a 1.75-inch compression tweeter for detailed, natural audio across a wide frequency range.

Its dedicated midrange, Directivity Matched Transition coverage, onboard DSP and EQ, and flexible mounting make it a high-performance main loudspeaker for demanding live and install work.

Product Description

The KW153 is a three-way system pairing a 15-inch woofer, a 6.5-inch midrange driver, and a 1.75-inch compression tweeter, driven by a pair of efficient Class-D amplifiers with a combined 1000W output. The dedicated midrange improves vocal and instrument clarity, while Directivity Matched Transition (DMT) keeps coverage even across the listening area.

Connectivity includes XLR-1/4-inch combo inputs and line-level RCA inputs, mixing up to three sources internally with per-channel direct XLR outputs and a mix output for daisy-chaining. Internal DSP includes Intrinsic Correction, DEEP, and GuardRail, and onboard EQ controls let you match the speaker to the room. A rear Phoenix connector accepts an external potentiometer (not included) for remote gain control.

A standard 35 mm pole socket, integrated M10 suspension points, and ergonomic cast-aluminum handles ease mounting and transport. For two-way models, see the QSC KW152 and QSC KW122.
