    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

    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.
