Another benefit of the high freq passive crossover...
often tweeters are more efficient and you can afford to
take loss in the crossovers... a hidden benefit.

I agree with Magnus that active crossovers are the only way
to go for concert sound... now for my little two piece band its
another story.  One big amp is much easier to deal with than the
tons of crossovers, amps, extra wiring...

Now of course if Magnus likes to send me a free trial system with active crossover...   :^P
