The M-F3A FS is the much-requested flyable bass extension module for the popular M-F3A and the new flagship M-F3A PRO line array systems. By employing two specially designed 6” x 9” woofers, the subwoofer offers a slim and discreet design. The height is approximately twice the size of two M-F3As, complementing the overall system dimensions.

The unit contains a newly designed 800W Class-D power amplifier and is equipped with 24-bit/48 kHz DSP. By using the LCD screen and rotary encoder, users can control various system parameters such as delay, EQ, filters and more. Configurations then can be saved as user presets. In addition, the built-in factory presets reduce setup times for existing M-Line systems in various configurations.

When flown with M-F3A or M-F3A PRO, the unit can deliver rich and deep bass to manage simple applications. More demanding applications can be realized by pairing the system with S12 PRO subwoofers, thus working as a bass extension for low-mid frequencies.

Improved rigging capabilities and a newly-designed bumper frame gives additional flexibility to integrate this adaptable subwoofer into M-Line systems.


Two sets of woofers

Each M-F3A FS deliverrs a punchy and deep bass fundament. To minimize the size of the cabinet the efficiency was improved by the space-saving use of two arrays consisting of a dozen of aggregated smaller hight-tech bass loudspeakers at a whole.

Built-in DSP

Each M-F3A FS is equipped with 800W Class-D power amplifier with switching-mode power supply for minimum weight and maximum flexibility anywhere in the world. Additionally to that our 24bit/48kHz DSP processor provides signal filtering and ensures maximum driver protection with zero-failure rate.

EASE® Ready

AFMG® EASE® and EASE® Focus 3 GLL files are available for the whole M-F3A PRO family. This allows users to simulate and calculate various parameters such as audience coverage, SPL, frequency response, splay angles, delay times and more. Files are available in the Downloads section.
