Polk Audio LSiM703 is a beautiful speaker inside out yet some parts of the crossover might look better once replaced. For all those with urge to recap their speakers, here's the schematic I put together while meddling with my pair of LSiM703.

    Thanks for making the schematic, I'm sure many will appreciate it.

    Came to here, looking for this type schematic, but after following circuits, realized, there may be some mis-drawn connections on the high frequency and mids part of diagrams.

    Perhaps not, after looking more. Just hard to see before enlarging. Seems the mid has an unusual layout is all.

    Hi Hans,

    Here's a picture of the crossover for you. It would be beneficial if you could double check my diagram, just in case.qfcdnni4zwo5.png

    Confirming here that the schematic is legit. Rebuilt two 703s - all works and sounds as it should.
