FASTīn Loud is a two way floorstanding speaker.

FASTīn Loud is a bass-reflex cabinet loudspeaker with drivers of Visaton .

The kit is delivered with the following drivers:
- a Visaton B 100 full range driver
- a Visaton PAW 25 woofer

The loudspeaker has been developed by Thomas Schmidt.

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 is perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 1% above 200 Hz and doesn't exceed 1% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

  • Visaton full range driver B 100 - 6 Ohm
  • Visaton woofer PAW 25, 8 Ohm
  • Bass reflex tube BR15.34, black
  • 0,5x PE sealing tape, 5x2 mm, 7.5 m

Kit without cabinet, price per speaker   EUR 310,00 excl. VAT: € 260.50 / $ 302.18

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 fullrange driver are of type polypropylen (MKP) Clarity-Cap CSA 630 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 20,52 excl. VAT: € 17.24 / $ 20.00

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 220x155 mm, order no. I-8805002, price per unit:   EUR 11,70 excl. VAT: € 9.83 / $ 11.41
We recommend one board per kit (2 boards per speaker pair)
