The model name is 220ms (IIRC) and you should be able to Google a fair bit of info about it. The dirver had been used in a few commercial products, most famously the Hotei (sp?) in recent times.I once very serously considered purchasing a pair of these, but something put me off. A recessed upper bass/lower midrange maybe or required more drive than I had on offer?.. I can't remember, so take that with a pinch of salt.
Great to hear they are still being produced. I may have to look into them again.
Cheers
