I have a pair of Polk TSX550t and am curious about how corssovers are done in most polk three-way towers.

The 550 has the tweeter on the top binding post and the midrange and woofer on the bottom.

I think that my old speakers have the tweeter and mid on the top post and the woofer on the bottom post.

What is the advantage and disadvantage of both ways?

    This question was meant to be when biamping, what is the advantage and disadvantage of both ways?

    Can't bi amp with a receiver, it's marketing hype...

    I understand that is not the best way to bi amp and I might get a separate amp, but I am asking about crossover designs now.

    It's not any way to bi-amp, period. You can't bi-amp with a separate amp either, you'd need 2 of them and active crossovers.
    but I am asking about crossover designs now.

    What goes where depends on the frequency points. I don't think there's an advantage/disadvantage either way.

    Thanks F1nut, for your reply about the crossovers.

    I understand about needing 2 amps to bi-amp a speaker. When I said that I might get a separate amp, I meant one with several outputs, not only one. I also know that using two separate amps in a receiver is bi-amping, in a fashion. It it using 2 amps even if it does not do any good.

    My original question was about the advantages and disadvantages of crossover design for bi-amping, not on how to bi-amp and you have answered that question.

    Thanks

    A power amp has among other things its own power supply. An AVR has a single power supply shared by all the amp channels, therefore it is not possible to bi-amp using an AVR or a single power amp or a multi-channel power amp as it too shares a single power supply.

    Thanks for the info on the multichannel power amps.
    I thought that they were completely separate amps and power supplies in a single case.
