Product Description
The QSC KLA12 12-inch Active PA Speaker delivers powerful, clear sound for professional venues and live events. With a high-power 12-inch low-frequency driver and 1.75-inch diaphragm compression driver, it produces dynamic audio across a wide frequency range from 44 Hz to 20 kHz, reaching a peak output of 131 dB SPL. Ideal for standalone use or as part of an array, the KLA12 offers flexible deployment, whether mounted on poles, flown in arrays, or positioned individually. Advanced DSP, including Ar-Q frequency optimisation and Tilt-Direct technology, ensures optimal sound and easy adjustment, while GuardRail protection safeguards against thermal overload and distortion. Its lightweight ABS enclosure makes the speaker easy to handle without sacrificing durability, and the powerCON input and thru connections allow seamless integration into existing sound systems. Whether for clubs, theatres, or outdoor events, the KLA12 combines articulate low-end performance, controlled high frequencies, and reliable construction for professional-grade sound reinforcement.

Impact-resistant ABS enclosure ensures portability and long-lasting reliability, while the SOLO Rigging System supports quick, tool-free deployment.
Massive Sound Reinforcement:
The KLA12 produces powerful, dynamic audio capable of filling medium to large venues. Its 12-inch low-frequency driver extends down to 44 Hz, providing rich, articulate bass without the need for subwoofers. The 1.75-inch diaphragm compression driver delivers clear and precise high frequencies, ensuring every performance sounds professional. Combined with extensive DSP, the speaker maintains consistent, distortion-free output across various environments, making it ideal for live concerts, theatre productions, and club settings. Standalone or in arrays, the KLA12 guarantees impactful and reliable sound reinforcement.
Flexible Deployment Options:
Designed for adaptability, the KLA12 can be used alone or in arrays with other KLA12 units or KLA181 subwoofers. Tilt-Direct technology allows easy adjustment of directivity for single-unit applications, while the SOLO Rigging System enables fast, tool-free array assembly. Its compact, lightweight design simplifies transport and setup, while multiple mounting options, including pole mounts and rigging points, ensure versatility in professional audio installations.
Optimised Performance and Protection:
With advanced DSP, the KLA12 ensures optimal performance while safeguarding its components. Ar-Q frequency optimisation automatically tunes the array, and GuardRail protection prevents thermal overload, clipping, and overcurrent issues. On-demand cooling and excursion-limiting transducer protection maintain reliability during demanding use. These features provide consistent, high-quality audio while extending the speaker’s operational lifespan, giving sound engineers confidence in any live setting.
