WaveMon 182/22 is a two way compact speaker.

WaveMon 182/22 is a bass-reflex cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW022WA05 tweeter
- a Wavecor WF182BD09 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 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 is nearly perfect.

At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,4% above 200 Hz.

Kit with high-end crossover

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 Wavecor TW022WA05 are of type polypropylen (MKP) Mundorf MCAP EVO Öl 450 V

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).

  • 0.7 mm air core coil, 0.15 mH/0.28 Ohm
  • ceramic resistor 8.2 Ohm/20 Watt

universal PCB

If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
