Concerto is a 3 way floorstanding-speaker that employs Visaton and Scan Speak chassis: woofer Visaton TIW 250 XS 8 Ohm, ring radiator Scan Speak R3004/6020-10 and two Visaton midrange chassis TI100. The floorstander has been developed by Thomas Reimann.
The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter, a 2rd order bandpass filter for the two mids. The woofer is connected to a 2nd order low-pass filter.
Between 70 Hz and 17 kHz, the frequency response is very linear on axis.

In the high-end kit we deliver for the woofer a baked varnish I-core coil instaed of an H-core coil. In the filter for the tweeter Mundorf Evo silver/gold/oil capacitors are used. Most inductances are 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)
