Kormoran is developed by Thomas Schmidt and Holger Barske. Kormoran is home to a Audiopur air motion transformer and a 14 cm mid-woofer Wavecor WF146WA02.
The crossover consists of a 3nd order high-pass filter (18 dB per octave slope) and a 3rd order low-pass filter.
"Units of cutting-edge technology. Very good and not expensive: That's the way a DIY kit should be. "
The high-end kit comes with high-value ClarityCap MKP foil capacitors, type SA. The inductances are baked varnished 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.
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 / $ 4.80
We recommend one board per kit (two boards for a speaker pair)
