Crossover parts for JBL L-26.

Our kit contains only the crossover parts of the K+T modification for the JBL L-26 speakers.

The loudspeaker has been developed by Thomas Schmidt and JBL.

The frequency response of this speaker is nearly linear.

The decay spectrum is nearly perfect.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,7% above 300 Hz and doesn't exceed 0,7% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

the crossover components (right),
to be mounted on a small wooden board.

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.
