ViMo is a compact loudspeaker with Visaton drivers. The kit is delivered with tweeter Visaton G25FFL on WG 148 R waveguide. In addition a Visaton woofer W 170 S 4 Ohm is employed.

ViMo has been developed by Frank Zeppelin.

The crossover consists of a 3rd order high-pass filter (18 dB per octave slope) for the tweeter. The woofer are connected to a 2nd order low pass filter (12 dB per octave slope).

The frequency response of this speaker is well balanced. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 1% above 200 Hz and doesn't exceed 1,5% at 95 dB at 1 m .

Our kit consists of

  • Visaton waveguide WG 148 R
  • Visaton G 25 FFL, 8 Ohm
  • Visaton W170 S, 4 Ohm.
  • Damping Sonofil 100 x 35 cm for 20 litres
  • Binding Post PK31, gold plated (one pair, red and black)
  • 1,5m Speaker cable 2x1.5 mm2, transparent
  • 1,5x Visaton Countersunk screws 3.5x25, 8 pcs
  • Plan for DIY kit

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. All capacitors are of type foil capacitors and in series to the tweeter Clarity-Cap ESA 250 V are employed.

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 12,60 excl. VAT: € 10.59 / $ 11.44

universal PCBs

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)
