M50ti is the right description. I have M40ti's, M60ti's and M2ti's... the VP100 is probably a ti as well, but it's in a box (replaced by VP180).

Also a bunch of newer Axioms. But I can quit any time.

I don't remember if there was a v1 or if Axiom went straight from ti to v2. I believe there was at least one generation before ti as well.

Does ti represent introduction of the titanium dome tweeter ?
