FBT Vertus CLA Line Array Column System with Subwoofer

Elite Acoustic Engineering: The Modular Performance Powerhouse

The FBT Vertus CLA 604A & CLA 208SA combo is a sophisticated, bi-amplified active line array system engineered for those who refuse to compromise between aesthetic elegance and raw acoustic power. By combining the clinical precision of the CLA 604A column with the high-excursion punch of the CLA 208SA subwoofer, this system delivers a linear, professional-grade frequency response from 50Hz to 20kHz. Ideally suited for touring musicians, high-end corporate AV installers, and rental production houses, the Vertus series offers a modular solution that excels in both live reinforcement and demanding fixed installations.

Precision Dispersion and Directivity
The CLA 604A column utilizes 6 x 4” custom woofers and 4 x 1” neodymium dome tweeters mounted on a specialised waveguide to provide a wide 100° horizontal and narrow 20° vertical dispersion. This configuration ensures superior sound projection over long distances while maintaining a consistent SPL distribution across the audience. For the performer, this translates to crystal-clear transparency and vocal intelligibility, even in acoustically challenging venues.

High-Efficiency Tri-Amplification
Driven by high-efficiency Class D power, the system delivers a combined 1100W RMS to achieve a massive peak SPL of up to 129dB. Integrated DSP processors in both units feature four dedicated equalisation presets, allowing you to instantly optimize the system’s dynamics and frequency response for various environments at the touch of a button. This provides the massive headroom required for live performance without the bulk of traditional PA systems.

Seamless Integration and Modularity
The Vertus system is designed for a clean, professional "stealth" appearance, featuring an internal XLR and Neutrik Powercon link system that hides unsightly cables from the audience. The columns are housed in rugged extruded aluminium, while the subwoofers use 15mm birch plywood, ensuring road-ready durability. A rapid latching system with pins allows for easy modular expansion, enabling you to double up modules to form a unified, coherent line source as your venue requirements grow.
