what he said...😉 you need to know about the woofer as well before making a sensible choice of crossover frequency
Sorry for the lately reply, this tweeter is diy product, isn't famous brand, so no model number.
Yes, you are right, the tweeter with a chamber. and the improved sample was finished today by my friend.

Denbo,
That FR is really very good. In all likelihood, the swings >10KHz are due to diffraction effects, and will look different (better) when mounted with care.
No doubt you could crossover this tweeter fairly low, around 2KHz. On the whole, the lower you can crossover your tweeter, the better it is.

Xmax?
Sd?
The lower you go, the more it has to move. One octave lower requires 4 times the excursion. Also- even if you have a low-Fs, this does not imply you can use it to 1.6kHz without other data.
There are maybe 10 tweeters on the home-market with an Fs of 500 or lower, but some cannot xover below 2kHz due to harmonic distortion rising harshly below there. Fs is not the only indication of performance.

Dear Wolf,
The up plate thickness(the air gap height) is 4mm, and the voice coil winding height is 2.3mm, so the Xmax is around 0.8mm, the Sd is 7 cm2. I know it is challenge for the 1.6kHz, but if the power is less than 30w for using at home, i think it is safe.
