Can anyone out there help me find a schematic for a China made Polk RT-105? Would like to upgrade caps. These speakers came with an old Onkyo compact system.

    If it was a simple 2-way bookshelf, the crossover is probably very simple. It might only have one capacitor and one inductor. Just take them apart and see what is there. Post photos of the crossover if you can.

    I have asked a friend at Polk to help with this, can you provide a photo of the front and back of the speaker?

    The crossover is mounted to the binding post plate. Remove it and the crossover will come out with it. You won't need a schematic as the crossover will be very simple with the values printed on the components, likely one cap, one resistor and an inductor. You should upgrade the resistor while you are at it.
