Over the last few weeks I've kinda got a speaker bug as I've been thinking
about 5.1 systems.
I came across a few sites regarding improvements to SBL/SL2/DBL/IBL range of
crossovers as they are all more or less identical.

As it now looks that I may be using my SBL's to part accomadate home theatre
along with my standard Hi-Fi, I've been chewing on the claims made of
improved sound performance through substituting better components within the
crossover.

I'd like to know on a cost basis if this really is a useful step upwards for
the speakers (rather than spending money elsewhere) & pick peoples brains of
useful tips on the subject.
If anyone has had direct experience to I'm all ears
