FBT Vertus CLA 604A Powered Line Array Column Speaker
The FBT Vertus CLA 604A is a powered column line array speaker designed for live performance, professional PA systems, venues, installations, houses of worship, mobile sound and event production.
This active column speaker features an extruded aluminium cabinet fitted with 6 x 4-inch custom woofers and 4 x 1-inch dome tweeters, each coupled to a wave guide for controlled sound projection. With internal Class-D amplification delivering 400W RMS for the woofers and 100W RMS for the tweeters, the CLA 604A provides strong output and clear performance from a compact, elegant column format.
The built-in DSP processor includes 4 equalisation presets, giving users quick setup options for different spaces and applications. A switch mode power supply helps keep the system efficient and practical for professional use.
The CLA 604A is part of the FBT Vertus CLA system, developed to deliver high-level sound quality, long-distance projection and better SPL distribution towards the audience. Its rapid latching system with pins allows multiple CLA 604A modules to be connected together, creating a unified column with increased SPL and improved low-frequency directivity control.
With compact dimensions, high horizontal dispersion and a refined appearance, the FBT Vertus CLA 604A is ideal for users who need professional sound without visually dominating the space.
Active Column Line Array Speaker
The CLA 604A is an active column line array speaker designed to deliver clear, controlled sound from a compact vertical enclosure.
500W RMS Total Power
With 400W RMS for the woofer section and 100W RMS for the tweeter section, the internal amplification provides dynamic performance for a system of this size.
6 x 4-Inch Custom Woofers
The speaker is fitted with six custom 4-inch woofers, helping deliver strong midrange and low-frequency performance in a slim column format.
4 x 1-Inch Dome Tweeters
Four 1-inch dome tweeters, each coupled to a wave guide, help deliver clear high-frequency projection and consistent coverage.
Built-In DSP with 4 EQ Presets
The integrated DSP processor includes four equalisation presets, allowing the speaker to be adapted quickly for different environments and sound requirements.
Rapid Latching Expansion System
The rapid latching system with pins allows the system to be expanded by doubling up CLA 604A modules, forming a unified column with coherent source integration, increased SPL and improved low-frequency directivity control.
Long-Distance Projection
The CLA system is designed for long-distance sound projection and improved SPL distribution towards the audience, making it well suited to live performance and venue sound.
Elegant Compact Design
The compact aluminium column design gives the listener focus on the sound rather than bulky speaker cabinets, making it suitable for visually sensitive installations and professional events.
High Horizontal Dispersion
High horizontal dispersion helps provide wider audience coverage, making the CLA 604A practical for venues, events, halls and performance spaces.
