Product Description
Created as a no-compromise choice for both live performers and installers, the VERTUS CS1000 compact line array combines maximum performance with a modular, scalable approach. Its lightweight but sturdy construction, blended with FBT’s distinctive engineering and elegance, has delivered a system that can be deployed on stage within minutes or discreetly integrated into the most delicate of decors to provide high-quality sound and controlled directivity.
Bi-Amplified Design
The system comprises a long excursion 12-inch bass reflex subwoofer and a passive mounted satellite, linked via a Neutrik SPEAKON connector and equipped with six full-range neodymium 3-inch drivers. Onboard the subwoofer is a Class-D, two-channel amplifier with switch-mode power supply, delivering:
600W RMS to the subwoofer
400W RMS to the satellite
Both are housed in birch plywood enclosures.
Innovative Storage Design
For ease of use, a storage compartment is provided within the subwoofer enclosure to securely house both the satellite speaker and its supplied mounting pole for storage and transport. A dedicated locking system holds all equipment in place.
Precision Mounting Pole
The mounting pole comprises three sections, allowing users to alter the height of the satellite to suit their requirements. A custom joint provides continuous vertical adjustment to ensure precise coverage in every venue.
Exceptional Coverage
No listener is left untouched by the VERTUS CS1000:
Horizontal dispersion: 110°
Vertical dispersion: 30° (+10° / -20°)
Precision placement of six 3-inch drivers forms a J-array
Dual Configuration – Maximum Power
The VERTUS CS1000 takes a modular approach — two systems can be used in a dual configuration to form a totally coherent and much more powerful solution. By stacking the two subwoofers and locking the two satellites together end-to-end (via the included VT-J 100 joining bars):
Maximum SPL is raised by 6dB
Vertical dispersion increases to 40° (+20° / -20°)
Horizontal dispersion remains consistent
Inverting the top satellite on each stack assures perfect phase cohesion
Build Quality and Ease of Use
Aluminium handles with rubber inserts for comfortable grip
Fanless amplifier module protected by die-cast aluminium
Onboard DSP with eight dedicated presets shaped by FBT’s proprietary algorithms
Satellite volume adjustment in 8 steps between -45 / +5dB range
Selectable high-pass filter for optimum reproduction
System Expansion – 8000W Peak
As your requirements grow, the VERTUS CS1000 grows with you — the CS 4000 package combines four systems in a two-per-side stereo configuration to achieve a remarkable 8000W peak output.
