If I already have a pair of 846A, are a pair of Carmels worth buying to play with for $700 especially if one of the Diaphrams is blown? I don't know anything about this speaker other than the 804A drivers were the predecessors of the 806A but aren't considered as good by some. But still, for $700, if I have the wherewithal to pick them up, would they be worth it or am I overspending for a speaker that can't rival my 846A no matter what I do to it? Thanks for the help!
