WaveOnWall 84 is a wall-mounted loudspeaker with a full range driver.
WaveOnWall is designed in such a way that it has enormous level stability, but should be supported by a subwoofer up to approx. 180 Hz. Such subwoofers are:
WaveOnWall 84 is a closed-cabinet loudspeaker with drivers of Wavecor .
The kit is delivered with Wavecor FR084WA01 full range drivers
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 full range driver.
- two a blocking circuits in series with the full range drivers.
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 0,5% above 200 Hz.

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 fullrange driver are of electrolytic plain.

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).
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:

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