Movi is a three way compact speaker.
Movi is a closed-cabinet loudspeaker with drivers of Monacor and Visaton.
The kit is delivered with the following drivers:
- a Monacor CP-308CX coaxial driver
- two Visaton W250S 8 woofers
The loudspeaker has been developed by Holger Barske and Thomas Schmidt.
The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the tweeter part of the coaxial drive,
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer part of the coaxial driver
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
The frequency response of this speaker is not perfectly linear. The decay spectrum as shown in the waterfall diagram shows some resonances also above 2 kHz . At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 1% above 400 Hz and doesn't exceed 2.5% at 95 dB at 1 m between 400 and 10000 Hz.

to be mounted on a small wooden board.
Note: We deliver foam in the form of egg crate, instead of hemp to dampen the cabinet.
Kit without cabinet, price per speaker - not available
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.

If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
