Tang Band Dschinn Mini-TL MTM floorstanding loudspeaker Kit with high-end crossover

Kit with high-end crossover without housing price per speaker

Dschinn Mini-TL MTM is a two-way floor-standing loudspeaker. Dschinn Mini-TL exists as a two-way loudspeaker with a bass-tweeter-bass arrangement or as a two-and-a-half-way arrangement with a tweeter, midrange loudspeaker and bass loudspeaker. Dschinn Mini-TL MTM is a transmission line loudspeaker with chassis from Omnes Audio and Tang Band. The loudspeaker contains the following chassis: - an air motion transformer (ribbon tweeter) Omnes Audio AMT50 - two woofers Tang Band W4-655 The loudspeaker was developed by Bernd Timmermanns. The crossover consists of: - a 2nd order high pass (12 dB / octave) for the tweeter. - a 2nd order low pass (12 dB / octave) for the midrange woofer. The frequency response of the loudspeaker is balanced. The decay spectrum is almost error-free. The non-linear distortions at medium volumes (90 dB, 1m) are below 0.4% above 300 Hz.

The high-end kit is equipped with baked varnish coils in the important places to reduce the microphonic effect (the current through the coil generates a magnetic field, which in turn sets the winding in motion. This movement induces voltages in the coil, which are added to the useful signal. The tighter the winding of the coil, the less the useful signal is distorted.) The capacitors for the Omnes Audio AMT50 - where quality is particularly important - are high-quality Mundorf EVO oil MKP capacitors with 450V.
