Jericho 23 is a floorstanding loudspeaker with a full range driver.

Jericho 23 is a horn loudspeaker with drivers of Dayton .

The kit is delivered with a Dayton PS 220-8 full range driver

The loudspeaker has been developed by Bernd Timmermanns.

The crossover consists of:
- two blocking circuits in series with the full range driver.

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1% 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 Dayton PS 220-8 are of type polypropylen (MKP) Mundorf MCAP EVO Öl 450 V.

  • Mundorf MCAP EVO Oil 3.9 μF / 450 V
  • Mundorf MCAP EVO Oil 8.2 μF / 450 V
  • Mundorf MCAP EVO Oil 33 μF / 450 V
  • Mundorf Hepta Coil II45, 0.22 mH/0.18 Ohm
  • Mundorf Hepta Coil II45, 0.18 mH/0.17 Ohm
  • Mresist Classic 4,7 Ohm / 10 Watt
  • Mresist Classic 22 Ohm / 10 Watt

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
  • 1.0 mm air core coil, 0.39 mH/0.29 Ohm
  • ceramic resistor 12 Ohm/20 Watt

Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 11,60 excl. VAT: € 9.75 / $ 10.43

universal PCB

If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. str-RA140, price per unit:   EUR 4,20 excl. VAT: € 3.53 / $ 3.78
We recommend one board per kit (two boards for a speaker pair)
