Mini Monitor Basic HP is a cheap small speaker that employs a Visaton W130 S4 woofer and the Visaton SC 10 N tweeter.
Mini Monitor Basic HP has been developed by Bernd Timmermanns.
The speaker is built in a closed cabinet with a high-pass filter with different crossover frequencies to harmonize perfectly with a subwoofer.
The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter. The woofer is connected to a bandpass filter (2nd order high and low-pass filter, each 12 dB per octave slope).
Between 100 Hz and 10000 Hz the frequency response of this loudspeaker is linear on axis. The decay spectrum is perfect. At low volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0.8% above 300 Hz.
We deliver Mini Monitor Basic HP with different cut-off frequencies to adopt it to a subwoofer. If you don't want to use a subwoofer, we recommend the the DIY kit Mini Monitor Basic without high-pass filter.

to be mounted on a small wooden board.
Kit without cabinet, price per speaker - not available
The high-end kit comes with 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.
Kit without cabinet, price per speaker on request
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
