    Those are the correct ones. You might want to wait until you can replace them all at once, otherwise you might experience audible imbalance.

    DAC: Arcam irDac

    I will have to wait some time.. my pre amp is going in for service next Monday. so it'll be down for a couple weeks.. that's when i'll replace those 4 tweeters.. once the pre is back. i'll fire every thing up again. but i can't get the other 4 silk tweeters till next month.

    i'm not to worried about audio imbalance. it'll give the first four tweets time to burn in. ;)

    Use those 4 to replace the two stereo tweeters in each cabinet. That's where you'll notice the most effect, and where they'll do the most good. Plus then your left-to-right balance will still be good :)
    Ludicrous gibs!

    I replaced two per unit, no problems. All I can say is they sound a heck of a lot better. I have one more per unit on order, and will wait till I get three in per unit to decide about the fourth.
    When I get the next two, I'm gonna do some testing on the SL2000's that I have remaining to see if I can hear any differences in them.

    Are these the same replacement tweeters that you would use for the SDA 1Cs as well?

    AFAIK, the RD0194-1 is the Polk replacement tweeter for the SL2000. I don't know about the "-A" nomenclature. Anyway, the RD0194-1 tweeters are the ones I used in my SDA 1-Cs to replace the SL200s.

    last night i installed 4 of the new silk dome tweeters in my SRS's. next month i'll replace the other four.. anyway, they look much better than the SL2000's. much more sleek looking now. Good visual upgrade.

    as for sound.. it's not noticeable yet.. since half of them are still the old tweeters.

    Oh yeah. does it matter which wire goes to what connection? the wireing being so old.. it wasn't labled very well back then. some of the wires had blue, white or beige tape on them.. some of the tape had fallen off over the years and some didn't have tape on them at all. i tried the connections both ways.. and didn't hear or notice any difference in the sound output.

    I believe the kunueter valve may be disconnected. Call Ken and see, my sl2000 had a post marked +. Seems there may be a phasing issue.

    Ted, some of my SL2000's also had a +, about 2 or them did.. not all of them.. they were manufactured in 8/86 the silks have a red connector and a plain connector. i figured the red on the new silks would be positive.

    I had a blown tweeter in one of my Polk 10's for quite a while and couldn't find anyone to help with the repair until I found this forum. THANKS to all you guys (y'all) for all the info. I now have two RD0194-1 tweeters on the way from Polk CS.

    Question--Is there anything that can be done to help prevent this in the future? I purchased these in 1986 and listen almost daily. Normal wear and tear?

    if they lasted you 20 yrs. i would think that would be normal wear and tear too.

    Yes, bow down and tell us how great we are at least once a week, or we just might buy up all the replacements ourselves. :D

    Actually, drive them with nice clean power to reasonable levels and don't hook/unhook while powered up and they will last another 20 years. Welcome to ClubPolk!!

    Aren't all 4 tweeters actually part of the stereo signal. I think they are in a progressive array so that they come in at different volume levels as needed, but aren't part of the SDA signal at all.

    Only the mids are used for SDA signals once they got to the reference series if I recall. Someone correct this old mind if I'm wrong............

    i'im not sure Dennis, but i have noticed that even though i've only replaced half of the SL2000's so far.. it has tamed the shrill a bit... I hope once i get the other four bought and installed.. the sound doens't become to laid back... i like nice detailed highs, but not to the point of shrill like the SL2000's.

    Yes, they come in at different levels. Polk discovered you dont need the tweet for SDA, so the SDA tweet was eliminated in later lines.

    You won't regret it.

    And : I don't think you'll find the replacements "too laid back". No lack of detail either. :)

    ok here's my latest findings... your milage may vary.

    installed the last 4 silk dome replacement tweeters in the SRS's... so they're done.

    Well, after listening to them for a few days... to ME they sounded laid back. I know you all are going to think i've gone loco or something. Maybe i was just used to the shrill for the past 8 months of living with the SL2000 tweeters to know any better.

    After two days.. i found myself touching the naughty knob... :p the treble!

    This compensated for the lack of detail I was missing. So tonight I replaced the interconncect from the pre to the amp.. with a (Raymond Cable) silver tinned biaxial cable. BAM!!! that did the trick.
    No longer did I need to touch the naughty knob anymore. it cured the laid back-ness of the new tweeters and it sounds amazing. The detail is spot on. Highs are sharp and detailed, spacious and full. mids are slightly forward, and bass is as good as it's always been.

    Years ago i tried pure silver interconnects... with little success. They were just way to bright for the KLH's i had at the time. Now fast forward years later and I am back to some form of silver wires again. Silver interconnects can be to bright for some people.. but with the right combo of components and speakers... they can be very detailed and revealing.

    Raymond Cable

    Al, that's a good review. Now you can enjoy your "new" speakers. :p

    Nice benefit there with the Raymond's which you already like. What type of cable were you previously using from your pre to amp?
