Omnes Audio Silver Line S is a two way compact speaker.

Silver Line S is a bass-reflex cabinet loudspeaker with drivers of Tang Band and Omnes Audio.

The kit is delivered with the following drivers:
- a Tang Band 25-2234SD tweeter
- a Omnes Audio MW 5.0 Alu woofer

The loudspeaker has been developed by Thorsten Fischer.

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 mostly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,5% above 250 Hz and doesn't exceed 1,2% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • Tang Band 25-2234SD
  • Omnes Audio MW 5.0 Alu
  • Bass reflex tube HP50, 50x145 mm, black

Kit with high-end crossover

The high-end kit is delivered with baked varnish air core coils 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 25-2234SD are of type polypropylen (MKP) Clarity-Cap ESA 250 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 15,40 excl. VAT: € 12.94 / $ 14.62

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 / $ 4.46
We recommend one board per kit (2 boards per speaker pair)
