PowerCor Home is a two way compact speaker. It is also available as a Powercor Professional with higher efficiency.

PowerCor Home 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 2nd order low-pass filter (12 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 0,5% above 300 Hz and doesn't exceed 0,7% at 95 dB at 1 m between 300 Hz and 10000 Hz. That is quite splendid.

Our kit consists of

  • Wavecor silk dome tweeter TW030WA11, 4 Ohm
  • Wavecor WF259PA01, 8 Ohm, professional woofer
  • Bass reflex tube HP100, 100x200 mm, black
  • 2,5x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)
  • 0,5x Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK28 I, gold plated (one pair, red and black)
  • 2m Speaker cable 2x1.5 mm2, transparent
  • 1,5x Allen wood screws, black, 4x25 mm, 8 pieces

Kit without cabinet, price per speaker   EUR 592,00 excl. VAT: € 497.48 / $ 557.18

Kit with high-end crossover

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.

Impedance correction

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).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 18,70 excl. VAT: € 15.71 / $ 17.60

universal PCB

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 11,70 excl. VAT: € 9.83 / $ 11.01
We recommend one board per kit (2 boards per speaker pair)
