Mona 17 is a two way compact speaker.
Mona 17 is a closed-cabinet loudspeaker with drivers of Monacor .
The kit is delivered with the following drivers: - a Monacor DT-352NF tweeter - a Monacor SPH-174KE woofer
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.
The frequency response of this speaker is perfectly 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 0,5% above 200 Hz.
the crossover components (right), to be mounted on a small wooden board.
Kit without cabinet, price per speaker EUR 211,00 excl. VAT: € 177.31 / $ 189.72
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 capacitor for the tweeter is of type polypropylen (MKP) Mundorf Mcap EVO Öl 450 V.
Kit with high-end-crossover without cabinet, price per speaker EUR 289,00 excl. VAT: € 242.86 / $ 259.86
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: 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)
