The Cordial is an high-end 2 way compact speaker with vintage look and modern drivers from Wavecor. The kit is delivered with Wavecor drivers of high quality: TW030WA11 tweeter and a Wavecor WF223BD02 for the bass range.
CorDial is developed by Holger Barske und Thomas Schmidt.
The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter, a parallel capacitor for the serial resistor increases the frequency response above 10 kHz. The woofer is connected to a 3rd order low pass filter (18 dB per octave slope).
The frequency response of this speaker are very linear. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.2% above 400 Hz and stays below 0.5% at 95 dB at 1 m.

Kit without cabinet, price per speaker EUR 523,00 excl. VAT: € 439.50 / $ 452.68
The high-end kit is delivered complete with baked varnish 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 of type polypropylen (MKP) and in series to the tweeter Clarity-Cap CSA 630 V with copper matrix are used.

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 PCB 220x155 mm, order no. I-8805002, price per unit: EUR 11,80 excl. VAT: € 9.92 / $ 10.21 We recommend two boards per kit (four boards for a speaker pair)
