RCF VSA 1250 II 12×3.5″ Digital Steerable Column Speaker

RCF VSA 1250 II vertical steerable array speaker system

The RCF VSA 1250 II is a high-performance multi-amplified vertical steerable array designed for professional sound reinforcement in acoustically challenging environments. It uses advanced DSP technology to precisely control vertical sound dispersion, ensuring that audio energy is directed only toward the intended audience area while minimizing unwanted reflections from ceilings and floors. This significantly enhances speech intelligibility in reverberant spaces such as transport terminals, conference facilities, houses of worship, and public buildings.

The system is powered by 12 Class-D amplifiers, each delivering 50 W, driving 12 high-efficiency 3.5-inch full-range neodymium drivers. This configuration provides clear, consistent sound coverage with excellent articulation across the listening area. With a maximum SPL of 94 dB at 30 meters, the VSA 1250 II is optimized for medium-scale installations requiring precise vocal clarity.

Advanced 48 kHz / 32-bit DSP processing enables detailed control of beam steering, vertical coverage, and system equalization. The vertical beam can be adjusted from 0° to –40°, while coverage ranges between 10° and 30°, allowing accurate adaptation to different architectural layouts. Horizontal dispersion remains wide at 130°, ensuring broad audience coverage.

Fully RDNet-compatible, the VSA 1250 II supports remote monitoring, configuration, and system tuning. Multiple equalization presets such as speech, music, and custom settings allow flexible audio optimization. Built with an extruded aluminum enclosure, the system offers durability, efficient thermal management, and a discreet architectural design suitable for modern installations where aesthetics and performance are equally important.
