The M-F3A FS is the flyable bass extension module for the popular M-F3A PRO line array systems. Highly demanded, it employs two specially designed 6” x 9” woofers that in addition to high SPL, offer a slim and discreet design. The height is twice the size of one M-F3A PRO unit, complementing the system in every way.

The unit contains a newly designed 800 W Class-D power amplifier and is equipped with 24-bit/48 kHz DSP. Improved rigging capabilities and the newly-designed extended bumper frame gives additional flexibility to integrate this adaptable subwoofer into M-Line systems.

Two sets of woofers

Each M-F3A FS delivers a punchy and deep bass fundamental. 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 high-tech bass loudspeakers at a whole.

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.
