FBT Vertus CLA 604 Two-Way Passive Speaker

Product Overview

The FBT Vertus CLA 604 Two-Way Passive Speaker is a professional-grade passive column line array designed for fixed installations requiring high-quality sound and controlled directivity. The system incorporates 6x 4″ custom woofers with 1″ voice coils and 4x 1″ dome neodymium tweeters on a waveguide.

We recommend a 500W at 8 Ohm amplifier — this speaker will deliver 123dB SPL. Designed to work with the CLA 208A subwoofers, the CLA 604 is ideal for indoor installations in reverberant environments, improving both music and voice intelligibility by enhancing direct/reflected sound quality.

Available in white or black.
