LOL You are the coolest ADTG!
I'm a bit confused (to be fair I didn't read the whole thread..) as to why R doesn't like active crossovers? Aside from the expense, active crossovers are far superior to passive crossovers. Not only does going active allow you to do things you can't when going passive (like using drivers with huge sensitivity mismatches), but active solves a
big problem with passive crossovers--XO frequency shift with volume! If it wasn't so expensive, every speaker I build (I haven't built any yet
) would use active crossovers.
