have you tried crossing the mid from 50hz/24db to 2.5k/24db, and the tweeter at 3.15k? thats what i found best so far, at least in my car in my install. those were my initial settings and i keep going back to them. i never tried them at 3.15k for the mids and 5k for the tweets though, i'll try it just for the hell of it though.
if you think the mids sound good at 63hz/24db, try them at 50hz/24db. well unless you listen to rap and music like that, idk how well the mid would like playing rap at a 50hz crossover point but i don't listen to any.
and i agree about the power, the tweets don't need much at all, and the mids will take anything i can throw at them.
they do sound very very good active.
