Power Punk is a three way floorstanding speaker.

Power Punk is a dipole loudspeaker with drivers of Omnes Audio .

The kit is delivered with the following drivers:
- a Omnes Audio CX15 coaxial driver
- two Omnes Audio OBW15PA woofers

The loudspeaker has been developed by Baur Akustik.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the coax-tweeter.
- a band pass consisting of a 2nd order high pass filter (12 dB per octave slope) and a 2nd order low-pass filter (12 dB per octave slope) for the coax-mids-woofer.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.

The frequency response of this speaker is mostly 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 1,4% above 300 Hz and doesn't exceed 4,5% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • 2x Omnes Audio OBW15PA
  • Omnes Audio CX15
  • Binding Post PK31, gold plated (one pair, red and black)
  • 4m Speaker cable 2x1.5 mm2, transparent

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 Omnes Audio CX15 are 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).

  • Audaphon MKT CAP 3.9 μF; / 160 Vdc
  • 0.7 mm air core coil, 0.68 mH/0.70 Ohm
  • ceramic resistor 5.6 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 8,10 excl. VAT: € 6.81 / $ 7.42

universal PCB

If you prefer to mount the crossover components on a 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. str-RA240, price per unit:   EUR 8,60 excl. VAT: € 7.23 / $ 7.88
We recommend one board per kit (two boards for a speaker pair)
