Audimax Micro BE is a two way compact speaker.
Audimax Micro BE is a closed-cabinet loudspeaker with drivers of SEAS and SB Acoustics.
The kit is delivered with the following drivers:
- a SB Acoustics Satori TW29BN tweeter
- a Hobby-HiFI/SEAS 18MW12T woofer
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
The frequency response of this speaker is perfectly linear.
The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0.4% above 200 Hz.

Kit without cabinet, price per speaker - not available
The high-end kit is delivered with Mundorf copper foil coils or baked varnish air core coils for minimizing microphonic effects. - The current flow through the coil creates a magnetic field which sets the reel of wire in motion. This motion induces a voltage in the coil which adds itself to the signal. The stiffer the reel of wire is, the less the signal will be altered. Most capacitors are Mundorf MCAP EVO or EVO-Oil and one Mundorf MCAP Supreme silver/gold/oil 3.3 μF / 1000 V.
Kit with high-end-crossover without cabinet, price per speaker - not available
If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).
If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. str-RA240, price per unit: EUR 8,60 excl. VAT: € 7.23 / $ 7.73
We recommend one board per kit (two boards for a speaker pair)
