Omnes Black Array is a two way compact speaker.

Omnes Black Array is a closed-cabinet loudspeaker with drivers of Omnes Audio .

The kit is delivered with the following drivers:
- four Omnes Audio T25 H tweeter
- four Omnes Audio MW 5.4 woofers

The loudspeaker has been developed by Omnes Audio.

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 nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,4% above 300 Hz and doesn't exceed 0,4% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • 4x Omnes Audio T25 H
  • 4x Omnes Audio MW 5.4
  • PE sealing tape, 5x2 mm, 7.5 m
  • Damping Sonofil 100 x 35 cm for 20 litres

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 T25 H are of type polypropylen (MKP) Clarity-Cap CSA 630 V.

  • ClarityCap CSA capacitor 10 μF / 630 Vdc
  • Audaphon MKP CAP Superior 22 μF / 400 Vdc
  • Mundorf baked varnish air core coil BL71, 0.68 mH/0.71 Ohm
  • Mundorf baked varnish air core coil BL140, 1.0 mH/0.30 Ohm
  • MResist Supreme 1.8 Ohm / 20 Watt
  • MResist Supreme 33 Ohm / 20 Watt
