Default what are WLM DIVA speakers made of?

Hi. There is an Austrian producer called WLM. They have released a speaker called DIVA with a 10 inch paper coaxial 2 way transducers. They look quite like 10 inch paper tannoys. Did anyone come across those? Are there avaliable on the DIY market? Any XO designs maybe?

The link to the producers web page is here:

case closed. I've googled up the answer.

http://www.hi-fi.com.pl/news_txt.php?id=588 (in Polish) says it's made of Eminence Beta 10CX with APT-50 driver. Interesting. 200 $ speakers (for pair) sold for 4000 $.

I wouldn't be surprised if they use a certain American kit's crossover idea too.

it would be hard not to use the XO ideas from Eminence, as the driver has it's resonant frequency at 2.5kHz and is usable from about 3.5kHz up. That makes it necessary to cut the driver at 3.5kHz 3rd or 4th order electrical. The cone breaks-up lower than that, so there's not much to do about that with the XO. Just tune it to be in-phase with the driver and have relatively flat response.

Eminence sells kit XO-s for the coax set that cut at 3.5kHz 2nd orger woofer and 3rd order driver.
