I ordered a Behringer 3-way active crossover...

[snip]

The Kef crossover frequency between bass and mid is 400Hz, but I've
found that setting the active crossover to this gave me a rather muddy
sound on the upper bass. Initial tweaking would suggest that something
around 120-200Hz gives a better balance - need to play with this more.

The 'crossover frequency' specified for most speakers is a fairly 'nominal'
value. Also, if you are simply splitting the links I assume the internal LP
and HP filters in the speakers are still in the signal paths. Thus the
'best' setting for your active crossover/filter may be quite different to
that specified for the speaker when used 'normally'.

Initial impressions are that

If you can make up CDs of test sinewaves, etc, and have access to a
reliable sound pressure meter, then it would be interesting to see to what
extent the differences you hear correlate with any changes in overall
frequency response being produced by the active crossover, differences in
gain of the two power amps, and effects of the output impedances of the
amps.

Slainte,
