Could someone please let me know if the SL3000 tweeter and the RD0194-1 tweeters are the same item or not. I am looking at upgrading my SDA SRS speakers and my local Polk Agent has informed me they have SL3000 tweeters in stock but are these the same as the RD0194-1's and if not what is the difference?

He tells me the SL2500 were the replacement for the SL2000 that I currently have and that the SL3000 is the replacment for the SL2500, if these are the same as the RD0194-1's then this will save me importing any.

thanks in advance.

I had someone tell me the same thing about a year ago. Call again and ask for Ken, if he's busy ask for the tweeter by name RD0194-1. Helen could probably take care of you as well. Just a little confusion in the parts dept. is all.

The sl3000 (as we know it) is not the correct replacement and to my knowledge has been out of stock and production for awhile. Same goes for the sl2500.

The only tweeters that you can use in your SDA SRS's are the SL2000 or the RD0194-1. That's it, period.

The SL2500 did not replace the SL2000, nor did the SL3000 replace either of those. They were simply tweeters with different specs used in different speakers. Again, neither one will work properly in your speakers.

I wouldn't think the SL3000 would work to replace the SL2000 unless some changes were made to the cross-overs.

Not sure,someone will reply here in just a bit.

Sorry but I have only been in contact with the Australian Importer, emailed Polk US earlier with a view to ordering but no reply yet. I am in Australia ( just in case you missed that bit ) so you can see the situation and if these are the same units thay are already here so far less hassle.

thanks.

They can't be used because they have different electrical characteristics than the sl2000. They will fit and plug in and sound will come out but the design parameters are different. If you have NO other choice the sl2500 is the closest match.

Realize that your Aussie Importer has stock that's more 3 years old as the company and process that produced the tri-laminate material the domes were made out of discontinued production. The RD0's came out around 2003 for this reason.

Good luck and the best way to reach Polk is by phone, I know being in Australia is a bit of an issue.

The SL3000 is a far superior tweeter to the SL2500.

The SL3000 is a far superior tweeter to the SL2500.

That's not even remotely what he asked. The sl2500 is much closer electrically to the sl2000 and that's what I was referring to. If he had absolutely no other alternative the sl2500 is a better match. The sl3000 would not be a good match to his speakers electrically and not recommended.

The best solution is to get the proper silk dome which is the RD0194-1. Sheesh, this is how the wrong things get passed on and on and on.

Perhaps sonically in the correct application the sl3000 is superior but this isn't that situation.

You guys are missing the point. It can physically be done and it is a Polk driver it's just not the best choice based on how the speakers were designed. They were designed using the drivers already in place. All the MW65xx mid-bass drivers are different in that they have different electrical characteristics one being the impedance. Same for the (5) different tweeters Polk used in their vintage Monitors and SDA's. Physically they are all interchangeable but electrically and sonically they are different. If they weren't then we'd have a single Polk tweeter and not (5).

Enough already.

Remember the SL-3000's I had in my SDA-1C's back when I got them last year? The original owner said that the Polk dealer had put them in there as an "upgrade" for someone and they had that 7.5-ohm resistor on them. At least that's what I think it was anyway. I'll have to dig back thru the threads and see.

I still changed the 3000's out for the RD0-194's and they sounded much better. Much Better. (yeah, I said that twice)

Edit: Nope, it was a 5W 5-ohm 5% resistor per this thread (http://www.polkaudio.com/forums/showthread.php?t=51651).

H9, do I read you right that all the MW65 bass/Mid drivers are different and need to be kept in their original position in the array to maintain the correct effect?

All my drivers were marked exactly the same but I kept them in the same removed positions on reinstallation just to be safe as with the tweeters.

Needed this post to get me off the number 13 whew!

Well I'm just trying to keep things how they should be. It's really not a matter of opinion other than Candy....has put a different tweeter in the circuit without problems. There will be no smoke and fire but it will sound different and it may be positive or negative.

As far as the mid driver are concerned the SDA SRS's use the same drivers for both the stereo and dimensional drivers, being the MW6503. As F1 suggests try to keep them in the same position they were originally if possible. Not a huge deal if they aren't.

Some of the SDA models (like my 1C's) use 2 different model mid drivers (one model for stereo and one model for dimensional) and it's essential they be put back in the correct position.

Good luck and if you find getting the RD0's is too costly and you can get either the sl2500 or sl3000 locally I would most certainly check with Ken at Polk to see the best way to implement them into your project. They won't be exactly what you are looking for but being in Australia sometimes you have to do what you have to do. Polk has great customer service so I'm sure they will be able to get the RD0's to you as economically as possible.

The sl3000's in my 2.3's don't sound odd or unusual or out of place in any way. They're my 2nd favorite polk tweeter behind the sl2000's. I haven't heard the rd0198's, sl1000's or sl2500's yet.

Says one person? Compare the crossover diagrams between any speaker with a SL2000 and SL3000, they're different. They may seem fine to him because he doesn't know any better, or he loves super bright speakers. Obviously, you have no clue what you're talking about...again.

As if either one of you has any credibilty when it comes to even a basic understanding of how a crossover circuit works and since ronnie no longer owns any SDA's, that makes his comments even less relevant.

What your comments do reveal is that both of you have probably lost a good portion of your high frequency hearing.

If you connect a generic speaker to an existing Polk crossover....it will reproduce sound. Is that good sound? Who knows, it doesn't matter. It's sound.

Did a petition go around that I wasn't aware of? If you don't currently own SDA's, you have no opinion? Previous ownership means nothing I see, or is it personal?

How about the petition about purchase of Polk speakers in the last month or year(s)?

Aside from Viva la SDA, what do you actually do for Polk Audio?

1. You wanna make at least a little bit of sense?
2. Means he hasn't played around with his SDA's. Seemed pretty clear to me. Don't you dare preach about what is lame.

Doesnt, putting a drive or tweeter, with different parameters, in the mix, change the entire speaker? Changes the ohms, the responce, the wattage handling, along with phase and peaks and gaps in the frequency response?

Not saying its good or bad, but doesnt it change everything about that speaker?

3. Filler.

4. Then why are you here? I'm here because I have a love for the product, manufacturer and the family....you brought me here no? I wasn't an employee when that happened and had a pretty high post count prior to that fact. Do you think that was just fluff? I was just hanging out so I could be cool like you? Biding my time so I could become a bigger Ahole? You folks read way to much into what I actually do on a daily basis.

No. It was for Polk....and our forum, and our friends. The old days were the Golden Age and I rolled in on the cusp of that "era", and gained some solid connections and lifelong friends. You seem to confuse a couple phone calls and a few get togethers with the core that existed prior to the hype but that's because you're friendly....I'm not friendly.

Actually I compensate for any minor brightness in my tweeters by running the warmest, tubiest tubes I can find or putting a cap on them at the tweeter level and not at the x-over level. I'm mixing and matching to get the sound I like just like we're all doing with wires, cables, tubes, tweeters, and gear in general. There's no right answer in this hobby. It's all subjective based on our personal likes and dislikes.

That's all fine for you but for a new member who is trying to get the proper info about upgrading his SDA's your advice is confusing. You are certainly entitled to do what you like but I am trying to keep the OP from making frankenpolks and keep them as original sounding as possible.

I can buy a plug in play tweeter from Parts Express which would fit in my SDA's that doesn't mean that's the best solution. Let's keep things in perspective and try to guide a new member in the correct direction rather than helping him make frankenpolks.

Actually your further explanation as to why you did what you did is probably helpful to the OP so he can understand why you put a mis-matched tweeter in your SDA's.

02-01-2008, 07:00 PM

H9,
not confused ( to old for that ) but jeez it seems their is some underlying issues amongst the members that I would rather not get involved in. My course of action will be to get a full spec sheet on the sl3000 tweeters and contact Polk re their advice and if possible order a full set of RD0194-1 tweeters either direct or through my contact at the polk importer in Australia.

On another subject I looked at Lasareth's web site and excellent photos of how he bought his SDA'S back to life and I noticed his Crossover was nothing like the one's in my speakers! Mine have 3 wound coils and far more electronics with a large circuit board that it all hangs off so I am not sure what goes their.

I pulled the Crossoover out this morning and will take some photos of it and post so maybe someone could give me some background on how to approach the electronics upgrade as it doesn't seem to match the Pdf schematics either.

Did Polk make interim/experimental Crossover networks and maybe this is one of them ? I will also be stripping the second cabinet this weekend and starting the internal works so if I can get the tweeter issues sorted and Crossover as well then I should be half way their when they go back together.

Once again thankyou everyone for your comments and help.

F1nut

02-01-2008, 07:18 PM

Loco, you have SDA SRS's, Sal has SDA SRS 1.2TL's and that is why the crossovers are different.

Once again, the SL3000's will not work properly with your crossovers.

Loco57

02-01-2008, 07:38 PM

F1,
right got the tweeter situation RD0194-1's are the only replacement with my SDA-SRS speakers. SDA-SRS 1.2TL's are totally different animals even though they look the same on the outside right!

So based on this has anyone done the crossover upgrade on the SDA-SRS model speakers that it appears that I have? And if so what results did you have taking into account the tweeter upgrade and electronics upgrade, was it worth it or am I flogging a dead horse here?

I would like to see what is possible with these speakers considering the cabinet work to date and if the above modifications are worthwhile all could be fine in the end as I generally like to fiddle with things no matter what they are ( just ask my race bike mechanic).

Once again thanks for the info!

heiney9

02-01-2008, 10:05 PM

Is there some documentation from Polk as to what damage putting sl3000's in non TL's would cause?

This has been discussed before and I am still doing it in my 2.3's: http://www.polkaudio.com/forums/showthread.php?t=35350

No one ever said damage would occur if you used the sl3000 in place of the sl2000. The high frequency part of the x-overs just isn't optimized or designed to sound correct (the original sound intended by Polk) if a different tweeter is used in the circuit.

I think I explained why I felt we needed to keep things going in the right direction in this thread. Anyone can experiment and do what they want but he didn;t ask about experimenting with his SRS's.

All the critical frequencies are covered and they sound phenominal. Otherwise I wouldn't have left them in for over 2 years. They aren't as detailed and clear and precise as the sl2000 but they are a nice alternative to someone who isn't adventurous enough to put a cap on their sl2000's.

You just don't get it.............are you that dense? One could replace a MW6510 with a MW6503 but it wouldn't be correct. Glad you experimented and enjoy what you have made. It's not the proper replacement tweeter & THAT has been what this thread is all about. NOT, what can fit in the hole and make sound.

This isn't any different than the never ending cable debate which the standard answer appears to be "if you haven't tried it, your opinion means nothing".

It absolutely is different............the cdp or amp or reciever or preamp, etc. doesn't have a specific circuit in it designed to be used with a certain and singular cable to be coherent with the full spectrum of sound the entire speaker is designed to reproduce.

The end result is the same as in altered sound, but it's a poor analogy.

So I think we're in agreement now. The sl3000's were not designed to replace the sl2000's but it can be done without doing any damage to the speakers or the amp and some have tried it with great results. Polk has never come out and said it won't work or that it shouldn't be done.

If advice is given by someone who has no direct experience in the matter and I do then I'm going to share my direct experience everytime it's appropriate.

Who else has replaced their sl2000's with sl3000's? If no one has then no can refute the great results I had and continue to have doing so.

Oh my god you are dense, denser than a piece of 3/4" MDF.

Here's the original poster's question:

Could someone please let me know if the SL3000 tweeter and the RD0194-1 tweeters are the same item or not. I am looking at upgrading my SDA SRS speakers and my local Polk Agent has informed me they have SL3000 tweeters in stock but are these the same as the RD0194-1's and if not what is the difference?

He tells me the SL2500 were the replacement for the SL2000 that I currently have and that the SL3000 is the replacment for the SL2500, if these are the same as the RD0194-1's then this will save me importing any.

Read slowly, nowhere does he ask if anyone has used sl3000's in place of sl2000's and what those results might be. N-O-W-H-E-R-E. Your response was confusing because it didn't answer his question.

Again for the 3rd time, no one (speaking for myself here) is trying to discredit your opinion about the sl3000's you have in your SDA SRS's. What I have been saying all along is your responses were confusing because you didn't answer his question instead you went off on another tangent, similar yes, helpful no.

The answer to his question is yes you can replace the sl2000 with the sl3000 which your local polk dealer has already recommended. If you don't like them, maybe the dealer will let you return them and then pursue the extra cost of ordering the rd0194's.

F1nut, I am glad that you have, finally, learned to respect the dung beetle. You should, as the dung beetle has a higher IQ than you!!!

You forgot to mention that you run tube equipment, warm cables, and can't hear over 2kz. :rolleyes:

I'm glad you like them, please don't pass this advice onto others though.

I do advise everyone to try it and see if they like it but a easier experiment is to connect a $3.00 2.0-2.2uf/50v mylar cap to the positive lead of the sl2000 which I've tried and also highly recommend. You can do the same thing to the sl3000.

I'll just stick with my RD0-194's which sound perfectly fine to me. I had the SL-3000's in the SDA 1C's when i got them and they were changed out not too long after that. Sure, they worked and played but, speaking from MY personal experience as someone that HAD them in there, I would get the RD0's. MY ears didn't like how they (SL-3000's) worked in that setup.

The answer to his question is yes you can replace the sl2000 with the sl3000 which your local polk dealer has already recommended. If you don't like them, maybe the dealer will let you return them and then pursue the extra cost of ordering the rd0194's.

Not true. He asked two questions:

"Are the 3000's the same as the 194's" ?

and

"If not, what are the differences" ?

Everything else is potentially informative but has nothing to do with the questions asked.

Could someone please let me know if the SL3000 tweeter and the RD0194-1 tweeters are the same item or not. I am looking at upgrading my SDA SRS speakers and my local Polk Agent has informed me they have SL3000 tweeters in stock but are these the same as the RD0194-1's and if not what is the difference?

He tells me the SL2500 were the replacement for the SL2000 that I currently have and that the SL3000 is the replacment for the SL2500, if these are the same as the RD0194-1's then this will save me importing any.

thanks in advance.

He currently has the sl2000 and would like to know about the sl3000 compared to the RDO's. So (by reading between the lines, which I do so well:rolleyes:), he is replacing the his current sl2000 with either the sl3000 or the RDO's. Of corse he is getting his information from a local Polk agent, not Polk themselves.

..from what I understand...
