Frequently Asked Questions about SE Audiotechnik M-F3A FS

Can the SE Audiotechnik M-F3A FS speakers work independently?

The M-F3A FS is a subwoofer The active (powered) speaker is designed to extend the bass range of line array systems, especially when combined with the M-F3A PRO. However, thanks to the built-in DSP and flexible frequency filtering (LPF 80–250Hz), the speaker can still operate independently or in combination with other full-range speakers, as long as there is a standard XLR input signal.

Are speakers suitable for use in small spaces?

With a power of up to 800W and a maximum sound pressure of 131dB SPL, the M-F3A FS is best suited for spaces from 25m² to 150m² such as: mobile stages, hall sound, tea rooms, lounges, or professional events. If used in a space that is too small (under 20m²), users should consider reducing the gain or using EQ to avoid excess bass.

Does the speaker's built-in DSP require software control?
