Audio Systems: passive crossover, musical sound quality, passive crossover

Question
When you have a passive crossover connected with a midbass and a tweeter( which often needs less power), do you need to do something to make sure that only the right amount of power goes to the tweeter?
example: you have a passive crossover (300W) and a middbass(200W) and a tweeter (15W), you connect them to a 250W amp, does the power divides itself correctly to the tweeter and the middbass?

Answer
Well, the relative power to each driver is a function of sound quality, not power rationing.  The sound engineer who does the voicing or musical sound quality will adjust the power level and frequency characteristics as the sound quality is optimized.

The amount of music power at high frequencies is much lower than at low frequencies.  Acoustic energy at bass frequencies is much, much higher than  at the treble range of frequencies.  That is why system designers find lower power requirements for mids and tweeters - as you have observed.

So you must look at the crossover as a sound quality device, not a power rationing device.

Hope this helps.
