tweeter, after cap

value ?
hmm, low xo point, and several impedance peaks
low xo point says bigger paralel coil
I don't know, but maybe like 0.5mH, or bigger
but, considering the higher impedance peak, maybe the 'smaller' 0.5mH, with a resistor

a trick to find the 'right' resistor
mount any resistor, like say 6R8
hold a bigger resistor across, in paralel
22R or the like
makes the resistor smaller
listen for artefacts, like peaking, or dullness
if it doesn't sound better, mount a bigger resistor like 10R or 12R
repeat procedure with the paralel resistor
if it sound better, try with smaller, like 8R2

be aware that if you change something else, these adjustments may need to be repeated again, and again
funny thing is, you can hear those 'artefact' standing right next to the speaker, holding that bigger resistor

when you change something, do it only on one channel, and listen
try to detect which channel sound better
then change the other
and when you get both channels running alike, it may need further adjustment, again
and so it goes, back and forth
until some lucky day you hit the sweet spot
it takes time for sure

be aware of phase issues
its a killer
with training its easy to hear
its harder to find where the phase issue comes from
but also a matter of training and practice
at some point you will know exactly how your speaker reacts to anything you do
its a matter of being stubbern, and methodical

also be aware that if you adjust something, but have listened for some time to a maladjusted speaker, the wrong sound may have affected your hearing
you may not be able to hear a new adjustment properly until the next day

did anyone say it would be easy :eek::D
