A few years ago my neighbour had the same question about his KEF103's. I suggested that he spend some money improving the crossover components; that is, changing cheap capacitors for fine audiophile capacitors, etc. The sort of thing that no manufacturer can do.
Anyway, he went for it, I rebuilt the crossovers with premium components, and he couldn't be happier. The sound is similar to what he had, but far, far better: more refined, accurate, punchy, and easy on the ears. So if you like what you have, but ... Then I suggest that you upgrade the crossover. Don't change anything but the quality of the parts, so a 2uF cap is still a 2uF cap - just that the one you are putting in is an MIT RTX costing about 100 times what the original part cost.
You might need a new box to hold the new components, as they tend to be a lot bigger as well as more expensive. Parts can be obtained from Parts Connexion or Michael Percy.
DIY forever!
