Axiom is supposed to be offering the drivers (all of the may need to be upgraded depending on the manufacture date of your V2), along with the crossovers. But the initial estimated prices put it so it would be just about the same price as buying a new set of speakers. So unless you've got a custom finish, you may want to put your V2s up for auction at http://deals.axiomaudio.com/
, and use the Axiom Dollars to buy a new set.
