Preziosa is a small monitor with ribbon tweeter. The kit is delivered with an Expolinear TMT 130K woofer and an Expolinear RT-9 Pro ribbon tweeter. Preziosa has been developed by Thomas Schmidt.
The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter. The woofer is connected to a 2 nd order low-pass filter.
The frequency response of this loudspeaker is linear on axis. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 1% above 250 Hz and rises not over 1% at 95 dB at 1 m above 800 Hz.

The high-end kit is delivered with baked varnish air 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. All capacitors are polypropylen capacitors (MKP). The capacitors for the Tweeter are ClarityCap capacitors type ESA.

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 universal PCB instead on wood
