Zaurak is a three way floorstanding speaker.
Zaurak is a bass-reflex cabinet loudspeaker with drivers of Wavecor .
The kit is delivered with the following drivers:
- a Wavecor TW030WA11 tweeter
- two Wavecor WF120CU08 midrange / bass drivers
- two Wavecor WF223BD02 woofers
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a band pass consiting of a 2nd order high pass filter (12 dB per octave slope) and a 3rd order low-pass filter (18 dB per octave slope) for the mids-woofesr.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofers.
The frequency response of this speaker is perfectly linear. The decay spectrum as shown in the waterfall diagram is exemplary, above 500 Hz free of any disturbing resonance. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.2% above 400 Hz and doesn't exceed 0.5% at 95 dB at 1 m between 400 and 10000 Hz. That is quite splendid.

The high-end kit is delivered with 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 two mids-drivers and the tweeter are of type polypropylen (MKP): Clarity-Cap PWA and Clarity Cap CSA.
