J-Line is a floorstanding loudspeaker with a full range driver.
J-Line is a transmission-line loudspeaker with drivers of Esoteric Audio Devices .
The kit is delivered with a Esoteric Audio Devices E100HD MK2 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 perfect for a fullrange loudspeaker.
At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 0,4% above 200 Hz.

Kit without cabinet, price per speaker - not available
The high-end kit is delivered with copper foild 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 Esoteric Audio Devices E100HD MK2 are of type polypropylen (MKP) Mundorf EVO ÖL.
Kit with high-end-crossover without cabinet, price per speaker - not available
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 10,50 excl. VAT: € 8.82 / $ 9.44
If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit: EUR 5,90 excl. VAT: € 4.96 / $ 5.31
We recommend one board per kit (two boards for a speaker pair)
