Mikro-Horn 2015 is a bookshelf speaker with Fostex fullrange loudspeaker FE 126 EN. It has been developed by Bernd Timmermanns.

The crossover consists of a LRC notch filter wired in series. The wave trap reduces the level between 0.3 and 6 kHz.

Our kit consists of

  • Fostex FE 126EN, 12cm, full range, 8 Ohm
  • 0,5x Damping 10, 970 x 470 mm, adhesive
  • 0,5x 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

  • electrolytic capacitor, etched, 47 μF/100 Vdc
  • electrolytic capacitor, etched, 68 μF/100 Vdc
  • electrolytic capacitor, unetched, 3.3 μF / 70 Vdc
  • electrolytic capacitor, unetched, 4.7 μF / 70 Vdc
  • 0.7 mm air core coil, 0.33 mH/0.48 Ohm
  • 0.5 mm core coil 10 mH/3.48 Ohm
  • Mundorf H core coil H71, 6.8 mH/0.7 0hm
  • 2x Metal-oxide resistor, 10W 12 Ohm (brown-red-black)
  • Metal-oxide resistor, 5W 6.8 Ohm (blue-grey-gold)
  • Metal-oxide resistor, 5W 10 Ohm (brown-black-black)

Kit without cabinet, price per speaker   - not available

Kit with high-end crossover

Kit with high-end-crossover without cabinet, price per speaker   - not available

universal PCB

If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. str-RA140, price per unit:   EUR 4,20 excl. VAT: € 3.53 / $ 3.78
We recommend one board per kit (two boards for a speaker pair)

Impedance correction

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).

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 13,20 excl. VAT: € 11.09 / $ 11.87
