I have pair of B&W CDM 9NT's and would like to biamp them. From all the info I've seen, the consensus seems to be that passive biamping is a waste of money. Active (which involves elimination of any crossover network in the speaker and the addition of an active crossover) is the way to go. I would like to be able to do this with the ability to put the crossover back in place when I upgrade to the 802's. Can anyone please tell me how easy it is to do this? I've never had a speaker open so I don't know what I'm even looking for. Is it just a matter of disconnecting a few wires then hooking them back later? Your help is appreciated. Thanks.
