Hi! I have had a set of RTI A9 and A7 speakers for 10 years or so, but haven't used them in recent years. I plugged them in and it seems like 1 of the A9 tweeters is shot and both of the A7 tweeters are shot. I think this is the problem, I am not 100% sure, but the highs seems awful in the two A7s and the 1 A9.

1. Are they easy to replace?

2. If I have two fxi a6's could I snag tweeters from them?

3. Does anyone have some I could buy?

Thank you for your help!!

Mark

    I checked with a friend at Polk and they have them in stock, part numbers:

    RTi A9 – Part # RD0697-2
    RTi A7 – Part # RD0696-2

    You can order from: 1-800-377-7655 and follow prompts to "parts department", they should just come away from the front baffle with simple tools.

    You should first figure out if the tweeters are actually bad and if so, exactly how they got that way.

    Ken, various online sites say the RTi A7 part # is RD0696-1. Did Polk change something?

    I think the "-2" is a revision indicator not a new part, Kim supplied the part numbers.

    My 2 cents: About 2010 I took inventory of the ‘A7 & ‘A1 drivers et al.

    Both used the RD0690-1. One had a “DPG21,” suffix whatever that means. As another posted the “-1, -2 is probably a batch designation of some kind for the bezel, meaningless for replacement purposes. They’re all the same tweeter. If you examine the RTi series you’ll see the same tweeter right down to the bezel.

    If you don’t mind doing a little surgery and saving some $*,PE sells a Peerless tweeter that black color aside looks just like the RD0690. IIRC someone used these in their B&W speakers; another for a Polk. Check the reviews and/or Q &A portion of the page.
    *$14 vs $65!

    Can’t see why not* - it’s the same tweeter! Should be a near no-brainer.

    Make certain** you have the right size Allen wrench for disassembly. Be very careful removing those screws - made of a soft metal that seems like aluminum though said to rust. Voice of experience** here - during reassembly ONLY hand tighten as the MDF strips very easily.
    **I believe Jesse will back me up on this

    Good fortune regardless of your course of action.

    Nice work Tony ;)

    My only question, If they go the faceless route is it easy to mount the new tweeter into the Polk OEM faceplate ?

    The stock screws are chrome plated steel with aggressive sheet rock type screw threads.

    I replaced every stock screw including the port screws by installing hurricane nuts and stainless steel cap screws. A job I will never do again and highly suggest no one attempt as getting to some of the holes from the inside is next to impossible. In fact, it's giving me a headache just talking about it.

    I hope you’re feeling’ better today.

    I followed your lead on this though limited the upgrade to mids, woofers, and 1 or 2 other stripped screw holes. I found the work not that tough. I filed the H-nut flange to clear the driver basket rims. Used black hex machine screws in place of the bright silver originals.

    Try doing the ports and you'll understand.
