hi
just need your expert feedback on some designs for some seas drivers.
i just need a starting point for my crossover to get things working ..then ill try and find some time to get a mic and software. Linearx stuff looks good but is a bit out of my price range.
anyway
have these drivers
seas millenium tweeter T25CF002 low resonance too
seas 6.5 inch magnesium mid w17e002
this mid has massive peaks at about 4.5k...how can these be tamed??
i was thinking about a 2k 24db x/o with impedence compensation
what type of impendence compensation do you also recommend??....parallel (resistor +cap in series with each other)
cheers jonathon

4.5kHz peak can be tamed with series LC combination parallel to driver- inductor should be 0.15mH and cap should be 4.7uF. As this combination is pretty effective you could even try 6dB/oct. with inductor at >2mH. Acoustic slope of such xover would be much higer than 6dB. Eventually you could need parallel RLC in series with that inductor to tame probable midrange hump.
I would go with 18dB/oct. with attenuation for the tweeter.
Although not a true recipe, I believe this is usefull.

You might want to check out Joe D'Appolito's Thor. It is an MTM with the millinium tweeter, but a different midbass.
