Xt19

[flux01]

I'm quite interested in building some speakers using the Vifa XT19 tweeter. I was thinking of using the Dillon Metaphor, substituting the XT19 for the Hiquphon OW1. Looking at their charts this seems resonable, but any comments would be appreciated.
Does anyone know of any designs with this tweeter and a good mid-woofer?
Thanks,

So has anyone used this tweeter? Any thoughts??

Looks like a great tweeter to me. I'm going to get a pair of those and possibly pair them with a Vifa 7" XG. Normally I wouldn't go any smaller than a 1" dome when used with a large woofer, but I get the feeling the Xt19 will handle it fine. The XG has reasonably smooth and extended response, and off axis response doesn't really begin to suck until 3khz. I'll probably cross over at 2.5khz, LR4. It's possible that both of these drivers will get to a target LR4 with only 2nd order electrical.

Dillon uses bottomless notches in his tweeter filters to simulate higher order rolloffs. You don't see that done very often and I question whether that topology is a good choice.
