hello

for passive filters, third order butterworth. the crossover point is -3dB(1/2)
so total sound energy is 1.
the low pass rolls off to -3dB, the high pass picks up at -3dB. it drops by half then increases by half. what about the dip. is that not something that would cause a problem. there would be a dip at crossover. is this a dip in sound? its a dip of -3dB, so it drops to half power, then increases by half power to where it started?

could someone go through this a little as I haven't been able to find any information on a number of sites that I have looked at.

cheers
simon

 

The filter slopes overlap. At the crossover frequency, half the power is being sent to one speaker and half is being sent to the other speaker.
