Monitor 10 tweeters

I have a pair of Monitor 10B's with silver coil SL1000's. I have a pair of
SL2500's that are coming out of my RTA15T's. I have read on other posts that the SL1000's are not very good tweeter's. Could/should I take the
SL2500's and replace the SL1000's? And if so would I have to modify the crossovers? Or would I be better off replacing the SL1000's with SL2000's?
I could do either but want some input which might be best. :D
Thanks

    Why do you want to replace the tweeter? Is there something you don't like about it?

    I guess I have heard that th SL1000's are not as good as others. I would consider this more of an upgrade. The SL1000's sound a little bright and tinny. Wondered if the SL2000's or 2500's would be possible.
    In your opinion would you stick with the SL1000's ?:confused:

    You can't use the SL2500's without a crossover mod. Your best bet, IMO, is to get a pair of RD0194-1's.

    Why not a pair of Peerless instead? And, to be honest, most of the "tinny" sound comes from the source. What are you using as source material?

    I don't believe you could use the Peerless tweeters either without modifying the XO's. The Peerless equipped speakers used an extra resistor in the signal path.

    I'd have to agree with F1, your best bet is to get a pair of RD0-194's.

    Peerless are overrated and the SL1000's are bright and tinny. It's got nothing to do with the source.

    I'd have to disagree with you there, but to each their own. Personally, I like the sound of the Peerless tweeters in my M7's more than the RD0's in my 2A's. Not that I don't enjoy the RD0's of course. They're both very nice tweeters IMO.

    I find Peerless tweeters dull.

    They were good tweeters for that era, but don't compare to modern tweeters.

    Ok. Sounds like some of this is personal preference. I have thought about replacing them with peerless, but they are hard to come by. But it looks like RDO's are the way to go if I am gonna change the SL1000's. Does that require any XO mods? Although I am planning on doing it later.

    I just pulled out my Monitor 5A's (Peerless) yesterday and i thought they were rather bright. I know that Polk made changes to the XO's along the way. there are at least 2 configurations for the 5A's. Looking at the values in my XO, I would expect them to be brighter than the other version. Bright or dull, it may be in the XO.

    Out of curiosity, what are the values of the resistors in your 5A's?

    Bright is the last way I'd describe the Peerless tweeters, but one persons bright is another persons dull I suppose.

    I'd call them more laid back, mellow and airy myself.

    Mine have a 2.5 ohm resistor I have seen other 5A's with a 6.2 ohm. I had posted pics somewhere around here a while back.

    If you're playing poorly encoded MP3's, there's your source of tinny-ness. If you have a poor source, you'll have poor music. It's unavoidable. Make sure that's not the problem. And while you're correct that they ARE bright and CAN be tinny, listening to them with proper sources MAY satisfy the owner--that they're not too bright or not too tinny.

    As for upgrading from SL1000's, just realize that you will have to open up the holes a bit to fit in RDO-194's.

    My 5B's had 2.7 Ohm resistors in them, seems like there was lots of variations. My 5B's were manufactured in 1985. They now have the RDO-194-1 tweeters and I've upgraded the X-overs. Have about a month of listening on them and I think that they sound better then when they were new. IMO

    I was playing with my 5A's again and I thing the brightness was due to setting on my AVR-888. When I hooked them up to my DRA-835R to compare to the RTA11TLs, the 5As were about the same brightness but somehow smoother in character. As one would expect, they certainly do not have the full bodied sound of the RTA11TLs.

    Good point; that's what scares me from going back-and-forth between Peerless and the RDO replacements depending on the model you have (I have both types of tweets in two types of speakers, but haven't been motivated to replace anything yet). You need a good seal.

    If you'd like to try some SL2000s, I'll send you two in the box that I'm sending for the frozen MWs. I'm going to send it out on Tue. or Wed. so let me know if you want to try some. To be honest, I find the 2000 to be awfully bright for music in general, but some people really like them a lot.:)

    So if my 7B's had the Peerless, which I loved before I blew them, and I get the RDO's, should I remove the resistor or should that work out ok until I get daring enough to try my hand a replacing caps? Thanks guys. Still looking for a couple Peerless too.
