M-F3A PRO is an ultra-compact active line array system which offers crystal-clear sound reproduction with punchy mids and studio-quality highs, due to its hornless design.

The unique PA sound is achieved by incorporating 8 high-efficiency 2.8″ neodymium mid-frequency drivers, and 7 pieces of 1″ direct radiation dome tweeters into each unit. All these drivers have been designed for high efficiency and extended LF bandwidth. In result, it helps to lower the cut-off frequency in the low-mid band, which makes the vocals sound exceptionally rich and natural.

All drivers are mounted on an A4-sized front surface. Each unit reaches up to 129 dB peak SPL and weighs only 8.3 kg, including amplification and DSP. The M-F3A PRO‘s distinct sound is achieved by a 2-channel 600 W class-D power amplifier, delivering 2x 300 W RMS into the high- and mid-frequency drivers.

Two controls, the Level and the Line Unit selection, offer precise adjustment of the key system parameters, such as attenuation and system voicing, depending on the unit count in the array.

Dome Tweeters

Each M-F3A PRO is equipped with eight 2.8" woofers and seven 1" dome tweeters. To reduce the dimensions of the cabinet and ensure high-fidelity sound, the dome tweeters form the centerpiece of its unique sound. It allows you to deliver hi-fi sound to your audience in a compact size with plenty of power.

Built-in DSP

Each M-F3A PRO is equipped with a 600W (300W HF and 300W MF) Class-D power amplifier with switching-mode power supply for minimum weight and maximum flexibility anywhere in the world. Additionally, our 24-bit/48 kHz DSP processor provides signal filtering and ensures maximum driver protection with zero failure rate.

Bremerhaven City Hall opts for an M-Line speaker system by German specialist


Jan Hendrik Banaschewski (Technical Manager):"In our search for a new sound system, we came across SE Audiotechnik from Solingen. We were promptly given the opportunity to have a demonstration of the M-Line in-house. Manne Sumfleth from SE-Audiotechnik, in cooperation with Blue Sound / Herbert Heinze as an executing partner (, demonstrated the advantages of the compact but powerful M-Line system."
