WaveMon 152-2.5 is a 2 1/2 way floorstanding loudspeaker that employs two Wavecor WF152BD06 woofers and a Wavecor TW030WA09 silk dome tweeter. WaveMon 152-2.5 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) with an parallel RCL for the lower woofer and a 3rd order low-pass filter (18 dB per octave slope) for the upper woofer.

Between 60 Hz and 20 kHz, the frequency response of this loudspeaker is nearly flat on axis. The decay spectrum is perfect. At low volume, i.e. 90 dB at 1 m, the nonlinear distortions are lower than 0,5% above 100 Hz.

Our kit consists of

  • Wavecor silk dome tweeter TW030WA09
  • 2x Wavecor Mid/Woofer WF152BD06, die cast
  • Bass reflex tube BR25.50, black
  • Damping Sonofil 100 x 35 cm for 20 litres
  • Audaphon Damping 10, 970 x 470 mm, adhesive
  • Binding Post PK31, gold plated (one pair, red and black)
  • 3m Speaker cable 2x2.5 mm2, transparent
  • Pan screws 4x20 black, cross recess, 4 pieces
  • Allen wood screws, black, 4x25 mm, 8 pieces

Kit without cabinet, price per speaker   EUR 448,00 excl. VAT: € 376.47 / $ 436.71

Kit with high-end crossover

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).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 12,50 excl. VAT: € 10.50 / $ 12.18

universal PCBs

If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. I-2766, price per unit:   EUR 5,10 excl. VAT: € 4.29 / $ 4.97
We recommend one board per kit (two boards for a speaker pair)
