Sonus Faber TWE283001 (from "Sonetto Center 1" loudspeaker)

TWE283001 - the tweeter from the Sonetto Center 1 loudspeaker of the famous Italian companySonus Faber.

The measurements were taken while modernization of two identical center channel loudspeakers to a stereo pair and are given for the best of the two tweeters. The HD measurements at voltage levels 2 - 4 Volt were carried out with High Pass Filter "on" (2nd order Butterworth type, 800 Hz cutoff, HPF2-800)

The tweeter has a very powerful neodymium motor, a 29mm dome fabric membrane produced by the German company Dr.Kurt Muller and proprietary D.A.D. (Damped Apex Dome) technology.

Both measured tweeters have a huge dip in the frequency response in the 10-20 kHz range. If this is the result of the D.A.D. technology, then, one asks, why is it needed at all? In any case, I did not notice any objective advantages from its use.

In addition, when the voltage is increased to 4 volts, both samples show a sharp increase in harmonic distortion, accompanied by audible parasitic sounds.
