Wavehorn is a floorstanding loudspeaker with a full range driver.

Wavehorn is a horn loudspeaker with drivers of Wavecor.

The kit is delivered with a Wavecor WF120CU07 midrange / bass driver (here as full range driver).

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of two notch filters to reduce the loudness in the mid and highrange.

The frequency response is linear except un aberration at 150 Hz. The decay spectrum as shown in the waterfall diagram is free of any disturbing resonance. At a volume of 90 dB at 1 m, the nonlinear distortions below 0,5% above 200 Hz.

Our kit consists of

  • WF120CU07, Wavecor Mid/Woofer, 8 Ohm, paper cone , BD, alu phase plug
  • Bass reflex tube HP50, 50x145 mm, black
  • Damping Sonofil 100 x 35 cm for 20 litres
  • 0,5x Audaphon Damping 10, 970 x 470 mm, adhesive
  • Binding Post PK31, gold plated (one pair, red and black)
  • 0,5x Pan screws 3.5x17 black, 8 pieces
  • Plan for DIY kit

  • ClarityCap PWA capacitor 4.7 uF / 160 Vdc
  • ClarityCap PWA capacitor 15 uF / 160 Vdc
  • ClarityCap PWA capacitor 33 uF / 160 Vdc
  • 1.0 mm air core coil, 0.33 mH/0.26 Ohm
  • 1.0 mm air core coil, 0.033mH/0.08 Ohm
  • 2x Metal-oxide resistor, 10W 4.7 Ohm (yellow-violet-gold)
  • Metal-oxide resistor, 5W 22 Ohm (red-red-black)

Kit without cabinet, price per speaker   EUR 199,00 excl. VAT: € 167.23 / $ 193.98

Kit with high-end crossover

The high-end kit is delivered with baked varnish air core 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. The capacitors for the fullrange driver are of type polypropylen (MKP) Clarity-Cap ESA 250Vdc.

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 1,60 excl. VAT: € 1.34 / $ 1.56

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.. I-2765, price per unit:   EUR 3,70 excl. VAT: € 3.11 / $ 3.61
We recommend one board per kit (two boards for a speaker pair)
