If there is, I don't know of it. Some insight is to be gained by Polk having to re-engineer replacements for the SL2000 and SL3000 tweeters. I don't think it's that easy to find off-the-shelf tweeters that are close in performance and electrical characteristics to the originals.

Wow! Thank God for this article.
I have had a pair of Polk RTA11 TLs for years. I thought something sounded a little off. I never could figure it out until now.
I usualy listen to music in the background when I am doing something else but, once in a while I just put on an album and really listen to it. It was during those few and far between sessions that I would notice something. The stereo image was a little off maybe.
I thought it might be my imagination. I thought it might be a blown speaker element. I did all kinds of fequency tests through the speakers. Both speakers were able to recreate all frequencies. I did touch and listen tests to all of the speaker elements. There was no blown element.
All the speakers were fine yet, they definitely sounded different. Seemed like the problem area was with the high frequencies. Years ago, I noticed that one of the tweeters was silver and one of the tweeters was black. I didn't think about that for many years.
Finaly, I took the grills off and unscrewed the tweeters. One tweeter was an SL2500 and the other was an SL3000. They were clearly marked.
I'm not really sure why there are different tweetersin my speakers. I bought them from a local hi-fi store that has gone out of business since the 90s. Were they damaged in the store and repaired? Did Polk run out of SL3000s on the day they made my speaker?
Has anyone else seen an SL2500 inside an RTA 11TL?
So, I went ahead and ordered a pair of RD-0198s. That should fix the problem.
I just wanted to let you know how much I appreciate the time and effort that you put into this article. I will let you know how my new RD-0198s turn out.
Thanks so much.
