MIkro-Horn 2018 is a two way compact speaker.
MIkro-Horn 2018 is a horn loudspeaker with drivers of Wavecor.
The kit is delivered with the following drivers:
- a Wavecor TW013WA01 tweeter
- a Wavecor WF118WA05 midrange / bass driver
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
In series to the woofer a notch filter is used.
response is linear except un aberration at 150 Hz. The decay spectrum as shown in the waterfall diagram is free of disturbing resonances. At a volume of 90 dB at 1 m, the nonlinear distortions are lower than 3% above 200 Hz.

Kit without cabinet, price per speaker EUR 183,00 excl. VAT: € 153.78 / $ 186.08
The high-end kit is delivered with baked varnish air core 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.
Four capacitors for the fullrange driver are of type polypropylen (MKP) Clarity-Cap PWA 160.

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 140 x 102 mm universal PCB instead on wood:

We recommend one board per kit (two boards for a speaker pair)
