Omnes Audio Power Duo is a two way compact speaker.
Omnes Audio Power Duo is a closed-cabinet loudspeaker with drivers of Omnes Audio and Tang Band.
The kit is delivered with the following drivers:
- a Tang Band W5-1880 full range driver
- a Omnes Audio OBW15PA woofer
The loudspeaker has been developed by Blue Planet Acoustic.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- 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 (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 0.8% above 250 Hz and doesn't exceed 0.8% at 95 dB.

Kit without cabinet, price per speaker - not available
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 fullrange driver are of type polypropylen (MKP) Clarity-Cap SA 630 V.
Kit with high-end-crossover without cabinet, price per speaker - not available
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 240 x 165 mm universal PCB instead on wood:
Universal PCB RA240, order no.. I-2767, price per unit: EUR 7,60 excl. VAT: € 6.39 / $ 7.15
We recommend one board per kit (two boards for a speaker pair)
