Elysion is a two way floorstanding speaker.

Elysion is a dipole loudspeaker with drivers of Mundorf and ScanSpeak.

The kit is delivered with the following drivers:
- a Mundorf AMT25D6.1-R air motion transformer (ribbon-tweeter)
- a ScanSpeak 21WE/4542T00 midrange / bass driver

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 2nd order low-pass filter (12 dB per octave slope) for the mids-woofer.

The frequency response of this speaker is perfectly linear.

The decay spectrum is perfect.

At 90 dB and 1 m, nonlinear distortions are below 1 % almost everywhere above 50 Hz.

Our kit consists of

  • Mundorf AMT 25D6.1-R
  • ScanSpeak Ellipticor 21WE/4542T00, 4Ohm
  • PE sealing tape, 5x2 mm, 7.5 m
  • Binding Post PK28 I, gold plated (one pair, red and black)
  • 3m Speaker cable 2x1.5 mm2, highly flexible, transparent
  • 0,75x Allen wood screws, black, 4x25 mm, 8 pieces
  • 0,04x 100 pieces drywall screws 3,5 x 25, black galvanized
  • Plan for DIY kit

Kit without cabinet, price per speaker   EUR 1507,00 excl. VAT: € 1266.39 / $ 1405.69

Kit with high-end crossover

The high-end kit is delivered with 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. The capacitors for the Mundorf AMT25D6.1-R are of type Mundorf MCap Supreme Evo Oil.

Kit with high-end-crossover without cabinet, price per speaker   EUR 1675,00 excl. VAT: € 1407.56 / $ 1562.39

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 16,00 excl. VAT: € 13.45 / $ 14.92

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 / $ 7.09
We recommend one board per kit (two boards for a speaker pair)
