WaveMon 146 is a two way compact speaker.

WaveMon 146 is a bass-reflex cabinet loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW022WA05 tweeter
- a Wavecor WF146WA01 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 perfect.

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

Our kit consists of

  • Wavecor silk dome tweeter TW022WA05, 4 Ohm
  • Wavecor Mid/Woofer WF146WA01, 4 Ohm
  • 0,5x Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK31, gold plated (one pair, red and black)
  • 2m Speaker cable 2x1.5 mm2, transparent
  • Pan screws 4x20 black, torx, 8 pieces
  • Plan for DIY kit

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 OIL.

  • Mundorf MCAP EVO Oil 4.7 μF / 450 V
  • Mundorf MCAP EVO Oil 10 μF / 450 V
  • ClarityCap PWA capacitor 12 μF / 160 Vdc
  • Mundorf baked varnish air core coil BL71, 0.22 mH/0.34 Ohm
  • Mundorf baked varnish air core coil BL140, 1.0 mH/0.30 Ohm
  • Metal-oxide resistor, 5W 2.7 Ohm (red-purple-gold)

Kit with high-end-crossover without cabinet, price per speaker   EUR 280,00 excl. VAT: € 235.29 / $ 251.76

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).

  • Audaphon MKT CAP 33 μF / 160 Vdc
  • 0.7 mm air core coil, 0.27 mH/0.44 Ohm
  • ceramic resistor 5.6 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 14,90 excl. VAT: € 12.52 / $ 13.40

universal PCB

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)
