Tweeter swap

Hi, I have a pair of RT800 3533. Both tweeters are blown. I have two pairs of RTFXLC 04590 for my 7.1 set up. Is it possible to take 2 of the tweeters from a set of the FX speakers to repair my RT800 speakers? If so, will my FX speakers still be able to work?

  • Ok thanks. I will take your advice. Should I use a multimeter to check to see if the crossover is still good?
  • Also, without pulling the FX speakers tweeter, visually they are not the same

    RTi A series tweeters:

    If I had to or wanted to replace them, am I forced to use the RDO 690s or could I use something else that comes/came w/other Polk speakers?

    No "why?" responses please.

  • Thank you for the help. I called Polk and they suggested RD2516-1. Gave me a price of 97.00 including TX and ship. for the pair. I installed them. My speakers sound amazing again. By the way I was able to check my xo with a multimeter per the tech's instructions. This forum gave me a good springboard.
