Facette AM is a two way floorstanding speaker.

Facette AM is a bass-reflex cabinet loudspeaker.

Facette AM is a loudspeaker with drivers of Audaphon and Wavecor. A passive radiator brings out a deep bass.

The kit is delivered with the following drivers:
- a AMT 1i air motion transformer
- a WF182CU12 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 tweeter.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer.

The frequency response of this speaker is perfectly linear. The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance. At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are lower than 0.3% above 500 Hz. That is quite splendid.

Our kit consists of

  • Audaphon AMT-1i
  • Wavecor Mid/Woofer WF182BD10 as passive radiator
  • WF182CU12, Wavecor Mid/Woofer, 8 Ohm, paper / glass fiber, BD, phase plug
  • 3x Damping fleece MT Bondum 800 (30 x 50 x 2 cm)
  • Damping Sonofil 100 x 35 cm for 20 litres
  • Audaphon Damping 10, 970 x 470 mm, adhesive
  • Binding Post PK31, gold plated (one pair, red and black)
  • 3m Speaker cable 2x2.5 mm2, transparent
  • 1,5x Allen wood screws, black, 4x25 mm, 8 pieces

Kit without cabinet, price per speaker   EUR 868,00 excl. VAT: € 729.41 / $ 897.18

Kit with high-end crossover

The high-end kit comes with Clarity Cap polyethylen capacitors (MKP). The inductances are Mundorf copper foil 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.

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 22,34 excl. VAT: € 18.77 / $ 23.09

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.. I-2767, price per unit:   EUR 7,60 excl. VAT: € 6.39 / $ 7.86
We recommend one board per kit (two boards for a speaker pair)
