  • size (HxWxD): 800 x 340 x 250 mm
  • frequency range (-8dB): 26 - 32000 Hz
  • crossover frequency(s): 1600 Hz

WaveMon 223 is a small floorstanding speaker that employs a Wavecor loudspeaker WF223BD02 and the fantastic Wavecor tweeter TW030WA12.

WaveMon 223 has been developed by Bernd Timmermanns.

The speaker is built in GHP technology (closed, with high pass filter).

The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter. The woofer is connected to a 3rd order low-pass filter (18 dB per octave slope) with a parallel RCL to smoothen the frequency response.

Between 35 Hz and 30 kHz, the frequency response of this loudspeaker is very linear on axis. The decay spectrum is perfect. At low volume, i.e. 90 dB at 1 m, the nonlinear distortion is below 0,3% above 200 Hz.

Our kit consists of

  • Wavecor silk dome tweeter TW030WA12, 8 Ohm
  • Wavecor Mid/Woofer WF223BD02 paper / glass fiber, 8 Ohm
  • 2x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)

Kit with high-end crossover

The high-end kit comes with Mundorf Silver Gold Oil capacitors in series to the tweeter. Three of the inductances are Mundorf copper foil 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.

Kit with low cost crossover

The low cost kit comes with cheaper crossover parts instead of the Hobby-HiFi standard recomments and it has a very good price to ratio performance.

universal PCBs

If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. str-RA240, price per unit:   EUR 8,60 excl. VAT: € 7.23 / $ 7.73
We recommend one board per kit (two boards for a speaker pair)
