I am looking to upgrade crossovers. Does anyone have the schematics?

I am new here. I am hoping that someone might have the schematics for the rti8, csia6, and rtia3. I purchased spare crossovers to practice on as I am not well versed in doing this type of work. Been reading a lot and admiring the work people have posted online. Just hoping for some guidance in this learning experience. Thank you.

    None of those schematics are available from Polk. I do have a hand drawn one for the CSiA6. For the others remove a crossover, all the values are printed on the components.

    Thank you. Anything helps. Do you have suggestions on components? I have read articles on types of resistors (Mills seems to be a safe bet), capacitors (Clarity, Sonicap), air core versus iron core. Equipment being used: Marantz 8802a paired with Parasound 855a/1000a. Second setup: Denon avrx4200 paired with Parasound 275v2.

    Personally I'd just do caps and resistors. Unless they got fried inductors do not go bad.

    I agree w/F1nut.

    you don’t need the schematics but this for RTi A3 could not hurt to have:

    I recall receiving one for the CSI A6 but that will take some time to locate.
