Audimax Floorstand BE is a two way floorstanding speaker.

Audimax Floorstand BE is a bass-reflex cabinet loudspeaker with drivers of SB Acoustics and Hobby-HiFi (Made by SEAS).

The kit is delivered with the following drivers:
- a SB Acoustics Satori TW29B-B tweeter
- a Hobby-HiFi (Made by SEAS) 18MW12T woofer

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
- a 3rd order high-pass filter (18 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 0,3% above 200 Hz.

Kit without cabinet, price per speaker   EUR 878,00 excl. VAT: € 737.82 / $ 826.35

Kit with high-end crossover

The high-end kit is delivered with foil and baked varnish air core coils on important parts of the crossover 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. The capacitors for the tweeter are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

Impedance correction

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).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 31,00 excl. VAT: € 26.05 / $ 29.18

universal PCB

If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. I-2766, price per unit:   EUR 5,10 excl. VAT: € 4.29 / $ 4.80
We recommend two boards per kit (four boards for a speaker pair)
