Just picked up a pair of rti70s, dropped em' in and both have blown tweeters. Thankfully I don't have much in them, and what reading tells me they most likely aren't worth fixing. You guys know if the is any interest in the woofers or baffles? Stinks buying a pair of speaks when you can't hear em first.

    That RTi series wasn't a very liked generation in the RT line. I had the 70s for a couple years and they were fine with me, but there were generations before and after that sounded better.

    That being said, why not see if you can get some replacement tweeters for cheap and see how you like them?

    Most ofthe reviews said what your saying. I'm going to call into Polk Monday or Tuesday and see what a replacement pair is. I would like to hear them, just to get my ears on another pair of polks.

    The RTi70 line lasted a little over a year where as most Polk lines last 3-5-10 years...

    I have a second HT system that has my old RTi70's, a CSi40, and a pair of RTi38's. It sounds really nice and the RTi70's dig deep enough that it works well without a sub. Not a speaker I would use for a music only system, but for HT they work fine.

    Polk has no replacements in stock. I've been trying to track down replacements for my 3000p's for quite a while now.

    I had read that there was an alternate tweeter that fits from Polk, any idea on that one? Seems like I'll have to part the drivers out and perhaps find a home for the cabs if anyone needs them.

    The RT3000p tweeter (the tri lam) was discontinued when the RTi70 series came out (silk tweeter) -

    There for a while they were interchangeable so I am guessing the RTi70 tweeter is discontinued?

    Looks like EBay is your best bet... Just remember those tweeters snap into the baffle, no screw holes

    Probably an obvious suggestion, but did you check the drivers to make sure it was the tweeter and not the crossover?

    crossover components would be easier to source than the tweeter.

    I have not checked the xovers, however just got off the phone with CS and they stated there has been two different tweeters avail, but nothing in stock. I don't think they support this line anymore. So, back to square one, whatever that is.

    I have bought used speakers before, hooked em up and the tweeter doesn't work. Open them up and low and behold the wired connecting the tweeter had come unplugged. On one pair of older polk (rt3s I believe) there was no sound coming from the woofer of one speaker and no sound coming from the tweeter of the other. Opened them both up and both had disconnected from the crossover, easy fix. Took about 10 minutes. Definitely worth a try.

    Take a look at the RTi70 schematic here. You will see that the 7.5uf cap (C1) that is blown in your crossover is indeed in the tweeter circuit. It's definitely worth it to try replacing it, as the cap will be inexpensive. However, just replacing the cap won't ensure that there aren't other components in that circuit that are faulty. Do you have a DMM that you could use to test the other components in the tweeter circuit?

    ...I would probably try replacing the cap anyway if I were you.

    I do have a DMM. For the going rate on these speakers, I'm think I may cut my losses and part them out. Although, if anyone semi-local to western NC wanted the pair, I could cut a very, very good deal as a project speaker....

    You're going to part out a pair of speakers because you need to replace two 10-cent capacitors??? Holy moly.. Good luck!
