ViPA-Fast   Floorstanding as in Hobby Hifi 1/2024

Technical data
  • impedance: 4 Ohm
  • sensivity (2,83V/1m): 92 dB
  • size (HxWxD): 1150 x 470 x 400 mm
  • frequency range (-8dB): 40 - 18000 Hz
  • crossover frequency(s): 220 Hz
  • speaker type: bass reflex

ViPA-FAST is a two way floorstanding speaker.

ViPA-FAST is a bass-reflex cabinet loudspeaker with drivers of Visaton .

The kit is delivered with the following drivers:
- a Visaton B200, 6 Ohm full range driver
- a Visaton PAW 38, 8 Ohm woofer

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the full range driver.
- 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 (waterfall spectrum) shows a decelerated swing-out behaviour in the mid-range.

At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 2% above 200 Hz.

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 Visaton B200, 6 Ohm are of type polypropylen (MKP) Clarity-Cap PWA 400 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 22 μF / 160 Vdc
  • ceramic resistor 6.8 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 8,30 excl. VAT: € 6.97 / $ 8.09

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 / $ 8.38
We recommend one board per kit (two boards for a speaker pair)
