FBT Vertus CLA 604 White

Vertus: A Column Designed for Integration and Clarity

Part of the Vertus series, the FBT CLA 604 W fits an "installation" approach: a slim column design that is easy to visually integrate, and controlled directivity to better manage sound dispersion in reverberant spaces. Its vertical format enhances intelligibility, a key factor when amplifying speech or ambient music at controlled volumes.

Intended Uses and Target Profiles

This passive column speaker is aimed at integrators, service providers, and venue operators seeking a reliable and elegant solution: conference rooms, places of worship, restaurants, hotels, retail stores, museums, or multipurpose halls. Thanks to the 100V line and its power taps, it is also suitable for multi-speaker installations over long cable runs, while retaining the option to operate at 8 ohms depending on the chosen audio architecture.

Projection, Intelligibility, and Wiring Flexibility

The CLA 604 W features a 2-way configuration combining six 4" drivers for a solid low-mid foundation and four 1" tweeters to add air and precision. The frequency response (-6 dB) from 130 Hz to 20 kHz confirms a speaker focused on clarity and articulation, particularly suited for voice and ambient music programs.

Controlled Directivity for Effective Coverage

With a stated dispersion of 100deg horizontal and 20deg vertical, this column helps concentrate sound energy toward the audience rather than the ceiling or floor. The result is more even coverage across the listening area and improved intelligibility, especially in rooms with complex acoustics.

Built-in 100V Line: Simplifying Multi-Zone Installations

The integrated 100V line transformer facilitates deployment in distributed installations. The 4-wire connectivity allows selection of mode and power (Com / +8 ohms / 50W / 100W) according to needs: optimizing coverage, adapting to the number of speakers, and coherent management of available power.

Power and Sound Level

With 500 W rms and a max SPL of 123 dB, the FBT CLA 604 W has the necessary headroom to cover comfortably sized spaces while remaining comfortable at moderate levels. The 3 kHz crossover ensures smooth transition between frequency ranges, delivering a balanced and clear sound.
