Wavemon 120/30 is a 2 way compakt monitor speaker with for the size very deep bassrange. Wavemon 120/30 has been developed by Bernd Timmermanns.
In Wavemon 120/30 is used a Wavecor WF120BD05 for the bass range and a Wavecor TW030WA13 for the tweeter.
The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter. The woofer is connected to a 3rd order low-pass filter (18 dB per octave slope) with two parallel RCL.
Between 40 Hz and 30 kHz, the frequency response of this loudspeaker is nearly flat on axis. The decay spectrum is nearly perfect. At low volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1% above 200 Hz.

The high-end kit comes with three Mundorf MCAP EVO Oil capacitors. Instead of two electrolytic capacitors unetched two polyester capacitors (MKP) of high quality are employed. The inductances are Mundorf copper foil capacitors or baked varnished 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.

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 240 x 165 mm universal PCB instead on wood:

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