FBT Modus 4820LA Active Line Array Speaker, 900W

The FBT Modus 4820LA Active Line Array Speaker is part of the Modus Constant curvature system it features 4x 8 inch neodymium magnet woofers and 4x 1 inch (1.7 inch voice coil) neodymium magnet HF compression drivers and a Vertical dispertion of 5 degrees x 90 degrees horizontal. The built in amplifier delivers 600/300w RMS at 137dB SPL.
MODUS is not just another line array in the market. It's the essence of ideas and use of technologies condensed into one focus: the invention of the most flexible sound reinforcement system able to satisfy the broadest applications, from live touring to permanent installation, without compromising quality and expectations.
MODUS is a constant curvature line array system comprising two modules, the MODUS 4805LA (5°V) and the MODUS 4820LA (20°V) each one equipped with 4x 8 inch neodymium magnet woofers and 4x 1 inch (1.7 inch voice coil) neodymium magnet HF compression drivers. The system is designed to achieve a very uniform distribution of SPL in the listening area in both large and small venues thanks to its total modularity. The constant curvature overcomes the limitations of line arrays with variable angles which inevitably create unmatched SPL between neighbouring enclosures at high frequencies.
The grouping of two "classic" array modules in one gives an amazing economic advantage and simplifies the setup of the system.
Two subwoofers are available for low frequency extension, both with mechanical suspension hardware to deliver seamless integration.
The MODUS 215FSA is a dual 15 inch subwoofer with a band-pass design and push-pull configuration, delivering significantly extended low frequency response despite its compact size. It is acoustically designed to support two or three MODUS 4805 or 4820 modules.
The MODUS 118FSA is a single 18 inch subwoofer with a bass-reflex design and compact dimensions that make it ideal for suspension. Designed to support one or two MODUS 4805LA or 4820LA modules and aesthetically similar to a 4805 module, the sub is capable of very high SPL in relation to its size. It can either be suspended above the line array modules or ground stacked. Additionally, the 118FSA can be used in conjunction with the 215FSA to further extend and reinforce low end performance.
