You don't have to remove the woofer to get at the adjustable
crossovers- and the backs are countersunk on the edges, for a really

a removeable back makes it much easier, than pulling each driver out.

Well, OK. But why would you need adjustable crossovers or access to
the wiring unless you were changing drivers?
