The QSC KW152 is a high-performance, 15-inch, two-way powered loudspeaker designed as a versatile main PA or powerful monitor solution for professional musicians, DJs, rental companies, and installed sound applications. As part of QSC's acclaimed KW Series, it integrates a robust Class-D power amplifier module, advanced DSP processing, and a carefully matched transducer system into a single, tour-ready enclosure. The speaker is built around a custom 15-inch low-frequency driver powered by a dedicated 1000-watt amplifier, and a 1.75-inch titanium diaphragm compression driver powered by a 500-watt amplifier, bi-amp configuration. This dedicated power and processing ensure optimal performance, high headroom, and minimal distortion, delivering clear, punchy bass and articulate high frequencies capable of filling medium to large-sized venues with authoritative sound.

A cornerstone of the KW152's performance is its sophisticated onboard digital signal processor (DSP), which provides precise system tuning and protection. The DSP manages crossover functions, driver equalization, and includes dynamic limiting to protect the components from overload and thermal damage. Users can select from several preset EQ curves optimized for different applications—such as Main PA, Monitor, Subwoofer, or Live—via a rear-panel selector switch, allowing for quick and effective optimization for the speaker's role in the system. The speaker also features Intrinsic Correction, a proprietary QSC technology that ensures uniform frequency response and phase coherence across its entire coverage pattern, resulting in consistent sound quality both on and off-axis.

Constructed with durability for the road, the KW152 features a rugged, multi-ply plywood cabinet with an impact-resistant, textured polyurethane finish. It includes ergonomic, recessed carrying handles, a sturdy 35mm pole mount socket, and multiple M10 threaded points for flying or mounting. The rear panel offers comprehensive connectivity with dual combo XLR/TRS inputs, a loop-through output, and a ground lift switch. With its combination of ample power, intelligent processing, roadworthy construction, and user-friendly operation, the QSC KW152 stands as a reliable and highly capable workhorse for a wide range of sound reinforcement scenarios where premium powered speaker performance is required.
