Mona 176 GHP is a two way compact speaker.
Mona 176 GHP is a closed-cabinet loudspeaker with drivers of Monacor .
The kit is delivered with the following drivers:
- a Monacor Monacor AIRMT-85 air motion transformer (ribbon-tweeter)
- a Monacor SPH-176 woofer
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1,5% above 200 Hz.

Kit without cabinet, price per speaker EUR 338,00 excl. VAT: € 284.03 / $ 298.24
Price for a pair of custom speakers of any color - not available (_)
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. The capacitors for the Monacor Monacor AIRMT-85 are of type polypropylen (MKP) Audaphon MKP CAP Superior 400 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).
Price per impedance correction for one speaker, to be mounted on a small wooden board. EUR 9,00 excl. VAT: € 7.56 / $ 7.94
If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit: EUR 5,90 excl. VAT: € 4.96 / $ 5.21
We recommend one board per kit (two boards for a speaker pair)
