FBT VERTUS CLA was created with the thought of integrating professional line array technology in an extremely compact and elegant speaker column.

Compared to the traditional two-way speakers, the sound is distributed much more evenly

throughout the audience, both in outdoor and in indoor environments acoustically difficult

or reverberating as well. The CLA cylindrical wave front boasts the pleasant effect of present

and precise forwardly projected sound. Even acoustic feedback towards microphones is reduced.


VERTUS CLA is a light and compact modular line array system created for both live and fixed

installations, comprised by two products:

CLA 604a: bi-amp two-way active column speakers 400 + 100W RMS

CLA 208Sa: active subwoofer 600W RMS




High-level sound quality from 50Hz to 20kHz expressly developed for live performance

Long distance sound projection and better SPL distribution towards the audience

Great and dynamic power performance thanks to tri-amplification system

Lightweight and easy to carry

Design and elegance for an easy integration even in the most demanding installations

Very compact dimensions enable the listener to concentrate on sound and not on speakers!

High horizontal dispersion


VERTUS CLA is a true professional line array system that can satisfy the musician looking for a compact PA solution, easily to carry, modular, ready to use in just minutes with no-compromise quality. It is capable of being integrated into any environment or installation requiring high-quality sound and controlled directional characteristics.
