The tweeter in my right-side R50 is nearly silent. I tried replacing the tweeter to no avail. Is it the crossover? If so what's the best approach to repair it?

Thanks

    The R50's and series are notorious for blown tweeters. I don't know if it's a design flaw with the tweeter, or maybe Polk overrated them as far as wattage handling goes.

    I have speakers that are years old that still work great, but I've burned up tweeters from this series of speakers - and I'm very careful about not overdriving or clipping.

    If you search around you'll find others as well.

    You can always double check by swapping sides that your speakers are connected to, then swapping tweeters between left and right. If the problems remains on the one speaker, then I would guess crossover. Not that you need to given you've replaced the tweeter, but it might help rule out you just go unlucky and got a bum replacement tweeter.

    When did you buy them? They have five year warranties.

    I don't know how the crossover is accessible in the R50, but it could be a loose wire off the crossover network. Have you checked the xovers?

    Hello,
    If I understand everything correctly you have replaced the tweeter but it still sounds as though the tweeter level is reduced, correct? If you're sure that none of your receiver settings are incorrect then the crossover would be the probable cause. To remove the crossover, first remove the tweeter and driver and disconnect their wires. Turn the speaker around and remove the input plate pulling the crossover and connecting wires attached to the input plate out of the cabinet. Package the crossover up and send it to Polk Audio, 2550 Britannia Blvd., Suite A, San Diego, CA. 92154. Please include a short note giving us your name, address and a copy of your sales receipt.
    Regards, Ken

    If you have a spare capacitor, you can use that to bypass the tweeter's cap and see if it is the cap that is causing the problem.

    If you're not desperate to get it working asap, send it to Ken for proper service.
