Thanks for the replies everyone!
Well, Ive been reading alot about GR reaserch and Danny mentioned he upgraded a pair of Paradigm Studio 60's previously. That caught my interest. Don't know which version he was talking about, but, if I can upgrade the crossovers in these things and apply some reso, might be worth it.
But, if they are just too old to help, then perhaps something GR reasech offers as a DIY kit may be better. Don't care so much about cabinet finish as much as SQ.
Perhaps, I can Keep the Cabinets, just replace drivers/crossovers?
