WaveOnWall-TL is a two way wall-mounted speaker.

WaveOnWall-TL is a transmission-line loudspeaker with drivers of Wavecor .

The kit is delivered with the following drivers:
- a Wavecor TW030WA14 tweeter
- a Wavecor WF120CU08 woofer

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.

The frequency response of this speaker is nearly 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 400 Hz.

Our kit consists of

  • Wavecor silk dome tweeter TW030WA14, 8 Ohm
  • WF120CU08, Wavecor Mid/Woofer, 8 Ohm, paper / glass fiber, BD, phase plug
  • 0,5x Damping Sonofil 100 x 35 cm for 20 litres
  • Female banana jacks, red and black
  • 2m Speaker cable 2x1.5 mm2, transparent

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 TW030WA14 is of type polypropylen (MKP) Mundorf EVO ÖL.

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 14,62 excl. VAT: € 12.29 / $ 14.12

universal PCB

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 4,97 excl. VAT: € 4.18 / $ 4.80
We recommend one board per kit (two boards for a speaker pair)
