I bought a set of R20s off of CL with blown tweeters, and I want to buy replacement tweeters and crossovers from Parts Express with the lofty goal of upgrading the sound - a fun EZ project for my teenage son and I. I have the choice of various crossover frequencies - 2, 2.5, 3, 3.5, 4, and 4.5 kHz. Any recommendations for these components? Thanks!!

    Why not just fix the crossover you have? Check with polk for tweeters if not search ebay for the correct tweeters. Crazy thought tweeters might be good and resistors are cooked.
    Have you checked the board?

    I have a set of R15's - the tweeter is the same, so I swapped them out - the R15 tweeters worked in the R20, so the crossovers in the R20 are OK. This project is mostly about buying some new components, and doing a little woodworking / soldering and learning about speaker building with my son. Just trying to make the best component selection upfront.

    So.
    You're planning on mucking about with speakers & modifying them a bit just so you can spend some time with your son?
    Maybe discovering what works & what doesn't work? Together?

    Rock on.
    There's no speaker made that is more precious than that.
    Have fun.

    I'd look roughly around the 3.0 -.3.5k range

    You got it! Thanks! 3-3.5 kHz seems right, and if we have to buy a couple to see what the effect is all the better. $ and fun before common sense for this project.
