Sonnenschein is a compact loudspeaker with a full range driver.

Sonnenschein is a closed-cabinet loudspeaker with drivers of Visaton .

- a xxTyp full range driver a full range driver

The loudspeaker has been developed by Holger Barske and Thomas Schmidt.

The crossover consists of a coil and a resistor to reduce the volume in the mid and highrange.

The frequency response of this speaker is nearly linear. Above 7 kHz the non-linear frequency response is typical for full range loudspeakers. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 1 % above 400 Hz and doesn't exceed 2 % at 95 dB at 1 m.

Our kit consists of

  • Visaton BG 20, 8 Ohm
  • 2x Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK31, gold plated (one pair, red and black)
  • 1m Speaker cable 2x1.5 mm2, transparent
  • 0,5x Pan screws 4x20 black, cross recess, 8 pieces
  • Plan for DIY kit

the crossover components (right),
to be mounted on a small wooden board.

  • Audaphon M core coil M12, 1.8 mH/0.18 0hm
  • ceramic resistor 15 Ohm/20 Watt

Kit without cabinet, price per speaker   EUR 60,00 excl. VAT: € 50.42 / $ 58.49

Important: The from K + T used amplifier electronic is not included in the kit.

Kit with high-end crossover

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.

Kit with high-end-crossover without cabinet, price per speaker   EUR 69,00 excl. VAT: € 57.98 / $ 67.26

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit:   EUR 4,70 excl. VAT: € 3.95 / $ 4.58
We recommend one board per kit (2 boards per speaker pair)
