Those are Eastech tweeters made in Malaysia for Monsoon multimedia speakers. Eastech bought Monsoon and then shut it down to get the licence agreement that Monsoon had with Eminent Technology.

They were XOed 2nd order to a 2.5" (and there was a separtely powered mono woofer).

I still have some and could likely estimate the XO.

There are also 2 versions of a larger panel that was used down to about 250 Hz (EQed below the 1kHz dipole rolloff).

THHHAAAAANKKK YYYOOOUUU VERY MUCH ! 😀

Are they worth something (the seller asks for 90 euros)???

And what do you think about the magnet placement for DIY ribbon twitter....

What do you know about the second pair ???

90 euro is WAY too much. 20 euro would be more like it. I'd sell a set for that, likely be double that with shipping.
