RE: Comment alimentez vous vos VOT? Quel est pour vous le meiilleur système?
Bonjour Pascal,
Parles tu des J321 ? Si c'est le cas, voici ce qu'en disait JMLC :
Quote
N°9 : Musique Concrète J321 Le Cleac'h horn + TAD TD2001 driver
Very low distortion. No H4 and H5 visible in the conditions of the measurement.
Extended response from 300Hz to 20kHz with a small negative slope above 8kHz.
Very flat and smooth frequency response curve. The classic hole of the TD2001 response around 1900Hz is annulled by the use of a 30ohm serial resistor. The group delay curve is very smooth and rises over 10centimeters (= 0.3ms) below 800Hz. This horn can be used on axis from 800Hz to 20kHz without any tweeter. The cleanest impulse response. Very few reflected energy from mouth to throat . Extremely low level of diffraction, HOMs...No breaking modes of the diaphragm. It may be difficult to find a bass loudspeaker having the same level of fidelity.

Donc 800 Hz...
Amicalement,
