Dunlavy speaker experts

I have some SCIVA's and I have some issues.  I really would like to talks with a dunlavy expert that knows the drivers and crossovers well.  Appreciate any help directing me to the right guy.
I have a mint pair of SCIVA's and have an opportunity to buy some SCV's.  Obviously I have to sale the ones I have and I want to talk to someone that knows both speakers and can give me good advice.
Try calling Pro Musica Audio in Chicago, IL 773 883-9500.
They are former Dunlavy dealers (1990's).
I’ll try to help.  Have been using the sciv since the 80s.     The ivA model used different bass drivers . But are pretty much the same speaker What issue are you having?   The Vs are a totally different animal
