Mirach is a two way wall-mounted speaker.
Mirach is a bass-reflex cabinet loudspeaker with drivers of Wavecor .
The kit is delivered with the following drivers:
- a Wavecor TW30WA14 tweeter
- a Wavecor WF152CU14 woofer
The loudspeaker has been developed by Daniel Gattig and Dennis Frank.
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.
The frequency response of this speaker is nearly linear.
The decay spectrum is nearly perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.6% above 300 Hz and doesn't exceed 0.8% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 314,00 excl. VAT: € 263.87 / $ 287.61
The high-end kit is delivered with a foil coil on the most important part 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 for the tweeter is of type polypropylen (MKP) Clarity-Cap ESA 250 V. The other one is a Clarity Cap PWA capacitor with 160V.

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
PCB 150x115 mm, tin plated, price per unit: EUR 4,70 excl. VAT: € 3.95 / $ 4.31
We recommend a half board per kit (1 board per speaker pair)
