Belaja is a two way compact speaker.
Belaja is a closed-cabinet loudspeaker with drivers of Audaphon and Accuton.
The kit is delivered with the following drivers:
- a Audaphon AMT 1i tweeter
- two Accuton C173-11-191E midrange / bass drivers
The loudspeaker has been developed by Dennis Frank and Daniel Gattig.
The crossover consists of:
- a first order high-pass filter (6 dB per octave slope) for the tweeter.
- a first order low-pass filter (6 dB per octave slope) for the woofer. To both loudspeakers a trap filter is in parallel.
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 low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,5% above 200 Hz and doesn't exceed 0,6% at 95 dB at 1 m between 300 and 15000 Hz.

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 capacitor in series to the tweeter is of type polypropylen (MKP) Clarity-Cap DTAC 630 V.

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 universal PCB instead on wood
