VisaWall is a two way wall-mounted speaker.

VisaWall is a closed-cabinet loudspeaker with drivers of Visaton .

The kit is delivered with the following drivers:
- a Visaton G 20 SC tweeter
- two Visaton FR 10, 8 Ohm woofers

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 2nd order low-pass filter (12 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 0,5% above 200 Hz.

Our kit consists of

  • 2x Visaton FR 10, 8 Ohm
  • Visaton tweeter G20 SC
  • 0,25x Damping Sonofil 100 x 35 cm for 20 litres
  • Female banana jacks, red and black
  • 2m Speaker cable 2x1.5 mm2, transparent
  • 0,5x Pan screws 4x20 black, 8 pieces
  • 0,5x Visaton Countersunk screws 3.5x25, 8 pcs

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 capacitor for the Visaton G 20 SC is of type polypropylen (MKP): a Mundorf MCAP EVO capacitor / 450 V

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 5,90 excl. VAT: € 4.96 / $ 5.50

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 / $ 3.45
We recommend one board per kit (two boards for a speaker pair)
