Detailed review of Sub Karaoke SE Audiotechnik M-F3

Eye-catching, compact design

SE Audiotechnik M-F3 Subwoofer is made from 15mm plywood coated with polyurea paint - an industrial paint used in touring equipment to resist scratches, moisture and abrasion.

Measuring 421 × 507 × 510 mm and weighing 28 kg, the M-F3 is both sturdy and compact enough to be easily moved. Rounded corners and a protective steel mesh front ensure the speaker is safe during transport.

Powerful speaker configuration and power

Inside the M-F3 are two 2mm (254-inch) woofers with 10mm voice coils and large ferrite magnets, creating a strong magnetic force that helps the speaker membrane respond quickly and accurately. The 51W RMS power is amplified by a Class D amplifier with integrated SMPS, ensuring high energy conversion efficiency and stable operation even when operating continuously at high intensity.

Outstanding sound pressure and performance

The SE Audiotechnik M-F3 achieves a maximum SPL of 129 dB @ 1m, enough to fill the bass of small to medium-sized stage spaces or high-end karaoke rooms. The frequency range of 40 Hz – 250 Hz (-6 dB) fully reproduces deep sub-bass and energetic kick drums. The adjustable low-pass filter design allows users to optimize the frequency crossover point to coordinate with full-range speakers.

Sound quality and control

The sound quality of the M-F3 is focused on solid, compact and well-controlled bass, limiting the phenomenon of buzzing or echoing. In EDM music, kick drums become decisive and powerful; in live music, the bass drum is clear and strong; and in karaoke, the bass supports the vocals to be thicker and warmer. The 0°–180° phase switch helps avoid bass cancellation when combining multiple speakers.

Signal connection and processing

The M-F3 features a 48 kHz/24 bit DSP that allows precise adjustment of cut-off frequency and volume levels. The XLR in/out port supports balanced signal connection, reducing noise and maintaining sound quality.

The Neutrik PowerCon power system allows up to 6 speakers to be connected to a single 220V power source, convenient for large sound systems. In addition, the speakers also have on, signal, limit, and protection indicators to help operators easily monitor operating status.
