Audimax Bookshelf BE is a two way compact speaker.
Audimax Bookshelf BE is a closed-cabinet loudspeaker with drivers of Hobby-HiFi (Made by SEAS) and SB Acoustics.
The kit is delivered with the following drivers:
- a Hobby-HiFi (Made by SEAS) 18MW12T woofer
- a SB Acoustics SATORI TW29BN tweeter
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
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 0,5% above 200 Hz.

For the speaker you need additionally ca. 36 cm of flexible aluminium tube NW63. You get it in specialist market for ventilation, or in online shops.
Kit without cabinet, price per speaker EUR 908,00 excl. VAT: € 763.03 / $ 846.96
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. One capacitor for the tweeter is of type polypropylen (MKP) Mundorf Supreme Silver/Gold/Oil.

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 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 / $ 4.76
We recommend two boards per kit (four boards for a speaker pair)
