Piezos, anyone?Paul S

I have a local friend of mine lent me PHY TW37 tweeter. It is French-made piezo driver:

I was running it last night and it was not as horrendous as I was expected. In fact it was almost nice. I do feel some “heaviness” in the sound of this driver, perhaps because it has fixed 12db/octave filter at 10kHz (too low for me) of because it users a relatively heavy paper cone. Also, the topmost region is kind of “dullish” to be a tweeter. I would feel more comfortable to use this driver as a “lower HF tweeter” then the “all-around tweeter”. I think that the “heaviness” in this tweet might be also because it futures a cone that sits in the moth of a little horn-like… horn and effectively acts as a reentry horn. The “horn-like horn” is filled with cotton that does absorb the highest frequency but should be less absorbent for lower knee of the HF.

Anyhow, dispute of everything, form this French-made piezo driver sounded more balanced then I expected. The biggest problem, in my case, was that this tweeter does have a deferent sound with my Vitavox S2 driver. If with Linaeum/TAD PT-R9 ribbons I might set them in a way that a deference between S2 and Linaeum/TAD PT-R9 would not be acknowledgeable then with PHY TW37 I was not able to do so It is not only about the fixed crossover point of the TW37 but rather different ability to be accelerated with dynamic and frequency range between this tweeter and my MF driver. All of this creates a different “feeling” of Sound…

Stull, the ribbons so far are leading the race…
