I'd like a method of balancing timbre 'till I get the sound I'm looking for.
as said, its not so easy
and its not just about adjusting level
phase and "timing" are the key words
voicing ?
probably means something different to different people
personally, Im not even sure I like the word
to me it implies something that isnt really true at all
first step is to have a crossover that makes sense
and you need to understand how the component works
individually, and together
then you have to "know" your speaker, and each individual driver
and how every small change in crossover affects it
different crossover topology appears to relate mostly to speaker design, more than to the choise of drivers
so, we need to know your speakers and crossover, to have any idea about what you are facing
you could start with small adjustments to tweeter
it might affect other xo functions
could be a beneficial sideeffect advantage, or not
