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

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.

CLA604A is an extruded aluminum column speaker fitted with 6 x 4″ custom woofers and 4 x 1″ dome tweeters, each coupled to a wave guide. The internal Class D amplification, 400W for woofers and 100W for tweeters with switch mode power supply and DSP processor with 4 equalization presets provide unexpected dynamics in a system of these dimensions.
The rapid latching system with pins allows for the expansion of the system, doubling-up CLA604A modules to form a unified column with an absolute and coherent source integration and increase of SPL and low-frequency directivity control.
