PowerCor Professional is a two way compact speaker. It is also available as a Powercor Home with lower efficiency.
PowerCor Professional is a bass-reflex cabinet loudspeaker with drivers of Wavecor .
The kit is delivered with the following drivers:
- a Wavecor TW030WA11 tweeter
- a Wavecor WF259PA01 woofer
The loudspeaker has been developed by Thomas Schmidt, Daniel Gattig and Dennis Frank.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum is perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.3% above 300 Hz and doesn't exceed 0.5% at 95 dB at 1 m between 300 Hz and 10000 Hz. That is quite splendid.

Kit without cabinet, price per speaker EUR 593,00 excl. VAT: € 498.32 / $ 553.13
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. The capacitor for the Wavecor TW030WA11 is of type polypropylen (MKP) Clarity-Cap CSA 630 V.

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
