Dschinn Mini-TL 2.5 is a two and a half way floorstanding speaker.

Dschinn Mini-TL exists as two way loudspeaker with woofer-tweeter-woofer arrangement or as two and a half way arrangement with tweeter, midrange loudspeaker and woofer.

Dschinn Mini-TL 2.5 is a transmission-line loudspeaker with drivers of Omnes Audio and Tang Band.

The kit is delivered with the following drivers:
- a Omnes Audio AMT50 air motion transformer (ribbon-tweeter)
- a Tang Band W4-655 midrange / bass driver
- a Tang Band W4-655 woofer

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

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 0,4% above 300 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 Omnes Audio AMT50 are of type polypropylen (MKP) Mundorf EVO Öl.
