Janne, they don't need the schmatic!!! I ordered my SonicCaps last month. I talked directly to I think Elliot and he took my order. I asked for a 1% tolerance, custom matched. He got me as close to the specs as possible.

Finally a reply from Jeff! Obviously he takes the weekend off! No respect for desperate upgraders.
I got the options to replace the 0.1 and 0.25 caps with Platinums and the 12 with 10+2 Dynamicaps. The 13.5 and 27 will be Sonicaps. Resistors as recommended. I will go for this option. Have to make it a little different 
He also recommended to cancel the polyswitch. If they now just could answer the #%$$# phone so I can place the order.................. HT/2 CH

He said Sonicaps was basic configuration. Then he proposed different upgrade alternatives. This was the highest configuration I thought would fit. Oil caps would have been too big.
I saw that many recommended to scrap the bypass. I will try with and without. I rather buy some extra stuff as the shipping will cost me a fortune anyway.HT/2 CH

Yep, that sounds like Jeff. He's always pushing something, which doesn't mean it's better, just different.
I'm looking forward to your impressions.Political Correctness'.........defined

I will also wait for your impressions with/without the bypass....I told you not to get convinced of buying them

Haha I know. Maybe I have to lie for a 700 USD upgrade. Maybe the Platinums do magic with the Dynamicaps.
Just talked to Elliot. The Platinums need 300 hours burn in time. Initially they will sound worse. I guess we have to wait and see.........HT/2 CH

Well I can tell you this, my Sonic caps were supposed to sound good after 200 hours of burn in. For some reason it took over 340 hours before they started sounding gooooooood. They could probably go another 50 or 60 more. I have another thread going about this. -

I am happy to hear that. The post of "upgrade going wrong" has been worrying me. I will give the full package 3-400 hours before I remove the Platinums. HT/2 CH

Hmmmm the XO parts just arrived. Caps and resistors from Soniccraft looks ok.
The Polk parts are without any kind of marking???? Boxes are clean as well as the tweeters?? Earlier atleast they were marked Happily Made in Mexico. The packing list describe it as TWEETER SL2500 SL3000 made in China.
Is this the good stuff or just some warehouse cleaning?

This is the good stuff. I believe in your photo the terminal on the right side is a red/purple color, this is the positive connection. The sl2500/sl3000 terminals are two different sizes so connecting is easy.

You are correct one terminal is red but the terminals are also different size. Does the RDO198 have same size terminals? Then I am screwed. :eek:HT/2 CH

Pics of the front of the tweet would help identify. The sl2000, sl2500, sl3000 have been out of production for a awhile now so I doubt that is what you got. The actual process of bonding the material to the dome on the original sl2500 and sl3000 tweeters was discontinued quite a few years ago. This is one of the major reasons Polk swithced to the silk dome.

There's no little labels stuck to the side of the magnets?, all 8 of mine had labels on the side.
There is nothing at all :eek: When I compare them to the old tweeters they just look like a poor chinese copy. The old ones have a silver dome. This one is black. The surrounding plastic is bulged on the old. This one is flat. No rubber around the dome on the new one either. There is no identification at all on these ones. Not even on the boxes they came in. The old boxes clearly said what was inside and the speakers where properly marked. Maybe I am worrying too much? I have mailed them and asked for an explanation. Your replacements looked like these ones? HT/2 CH

The one on the left is the new RD0. Absolutely nothing wrong with them or the way they are marked or shipped. They are completely different material used for the dome. The new ones are silk the old ones were Polyamide material which is no longer avail. So yes they will look different.
You are worrying WAYYYYY to much

Thanks. It looks like they flattened out the plastic a little more to save on material. For 48 bucks you would atleast expect a tiny little sticker with the part number. Haha maybe I stayed too long in China. Dont trust a thing from here. HT/2 CH

Here's the post from Ken I was looking for the other day.
This is from a 2002 discussion:
Dear Mr. Rausch,
Lauren has asked me to respond to your request for information on the RD0198-1 replacement tweeter for the SL2500 and SL3000 tweeters. The difficulty we faced, in trying to replace the SL3000, is not being able to purchase the Polyamide dome material, any longer. The original European manufacturer, of this dome material, is no longer making that material, nor is anyone else. Our engineering department drafted a comprehensive specification list, detailing mechanical and electrical characteristics and sent it to various potential vendors. These vendors then built prototype samples and submitted them for our evaluation. The engineering department compared the vendor's efforts against the standardized requirements. A qualifying vendor was chosen and Polk supervised production began. The result is the RD0198-1 which uses an advanced soft dome material as opposed to the material in the SL3000, but it exhibits the same frequency response, power handling, dispersion characteristics and impedance as the previous units. It allows us to continue providing replacement parts that we believe will satisfy Polk owners. As always, we welcome customer feedback and encourage owners to let us know what they hear.
Sincerely, Ken Swauger, Polk Customer Service"Appreciation of audio is a completely subjective human experience.

Janne,
the only thing I would suggest is not to put too much pressure on the screws when you screw in the new ones. As you notice in the comparrison of your 3rd picture that the structural webbing on the new one is a lot less than the old one.
I found out the hard way when I cracked one.

Haha I also cracked the first screw :mad: Did not see your post. The new sound is sweeeeet Compared first left original and right replaced. These chinese lookalikecopynopartnumber tweeters are kicking **** Cant wait to get started with the XOs now. HT/2 CH

I was looking at HTrookies XO upgrade and found something strange. My XO dont have the 22.5 resistor??? Did Polk forget it? Atleast they forgot to solder one of the silver micas in one end! I bought a 22.5 ohm so it is no problem. But why is it not there? It's in the schematic alright.:eek: This is now getting even more confusing. In the other XO There is no 2.7 ohm resistor. Instead there is a 22.5 ohm in its place The 15, 7.5 and 11.5 they seems to have been able to get in the right places. There must have been some serious drinking going on there at nights. HT/2 CH

He referred to his own thread in the beginning of this thread.
Lasareath also specifies 2 x 22.5 ohm resistors. My XO dont have them. Well one is there but it is placed where the 2.7 should be. The copper is shining on the PCB in the places where they should be so they have never been installed.HT/2 CH

I've had a pair of 1.2's and a pair of 3.1's; strange that yours do not have that resistor; maybe a previous owner messed with them; I know Polk has had different variations in crossovers in some of their vintage products, but I don't think this is the case with the 1.2TL's. Just put in everything that you bought (as in the schematics)_________________________________________________
