As Serge said in an old post above don't swap round any internal wires from the crossover!. They're supposed to be "out of phase" like that (not actually out of phase as such but look like they are). All you can really do is change the electrolytic caps and run them in a bit but don't expect them to sound anywhere near as good as KEF Reference 103.2's!!
