Power Duo W5-2106 is a two way floorstanding speaker.

Power Duo W5-2106 is a dipole loudspeaker with drivers of Tang Band and Omnes Audio.

The kit is delivered with the following drivers:
- a Tang Band W5-2106 full range driver
- a 15 inch Omnes Audio OBW15PA woofer

The loudspeaker has been developed by Baur Akustik.

The crossover consists of:
- a 3rd order high-pass filter (18 dB per octave slope) for the full range driver.
- 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 (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,6% above 300 Hz and doesn't exceed 1,3% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • 15 inch Omnes Audio OBW15PA

  • Audaphon MKT CAP 160 Vdc
  • Audaphon MKT CAP 160 Vdc
  • JB, electrolytic capacitor, bipolar 100 Vdc
  • Mundorf bs140 core coil
  • Mundorf H core coil H71

Kit without cabinet, price per speaker   - not available

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 capacitors for the Tang Band W5-2106 are of type polypropylen (MKP) Clarity-Cap PWA 400 V.

  • ClarityCap PWA capacitor 400 Vdc
  • ClarityCap PWA capacitor 400 Vdc
  • Mundorf, electrolytic capacitor, unetched 70 Vdc
  • 2x Mundorf, electrolytic capacitor, unetched 50 Vdc
  • Mundorf bs140 core coil
  • Mundorf H core baked varnish coil BH71

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).

  • JB, electrolytic capacitor, bipolar advanced, 22μF / 50 Vdc
  • JB, electrolytic capacitor, bipolar advanced, 100μF / 50 Vdc
  • Mundorf H core coil H71, 1.8 mH/0.34 0hm
  • ceramic resistor 4.7 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 18,50 excl. VAT: € 15.55 / $ 16.79

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit:   EUR 4,70 excl. VAT: € 3.95 / $ 4.27
We recommend one board per kit (2 boards per speaker pair)
