Mosel is a three way floorstanding speaker.

Mosel is a bass-reflex cabinet loudspeaker with drivers of Audaphon, BlieSMa and Accuton.

The kit is delivered with the following drivers:
- a Audaphon AMT160 Ultra air motion transformer (ribbon-tweeter)
- a BlieSMa M142A-6 mids driver
- two Accuton S220-6-224-FG woofers

The loudspeaker has been developed by Daniel Gattig and Dennis Frank.

The crossover consists of:
- a first order high-pass filter (6 dB per octave slope) for the tweeter.
- a band pass consisting of a first order high pass filter (6 dB per octave slope) and a first order low-pass filter (6 dB per octave slope) for the mids-woofer.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.

The frequency response of this speaker is perfectly linear.

The decay spectrum is perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,5% above 300 Hz and doesn't exceed 1,5% at 95 dB at 1 m between 300 and 15000 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 Audaphon AMT160 Ultra are of type polypropylen (MKP) Clarity-Cap CMR 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).

  • Audaphon MKT CAP 8.2 μF / 160 Vdc
  • Audaphon MKT CAP 47 μF / 160 Vdc
  • 1.0 mm air core coil, 2.2 mH/0.89 Ohm
  • 0.7 mm air core coil, 0.15 mH/0.28 Ohm
  • 2x ceramic resistor 8.2 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 41,00 excl. VAT: € 34.45 / $ 39.97

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 11,80 excl. VAT: € 9.92 / $ 11.50
We recommend one board per kit (2 boards per speaker pair)
