I just recently brought my things back from California. Among my things were my pair of 2.3tl's and to my dismay, 2 of the tweeters were damaged. The heat inside of my storage unit had distorted the diaphragms and thus killed them :( . I called Polk to see if replacements were still available. Wouldn’t you know it, they just ran out of the SL3000's and they are in the process of looking for a comparable replacement ( In 6 weeks or so). I realize Polk will probably want to replace them with original spec'd units. I just wondered if it would be more worth it to buy some Vifa ring tweets and modify my current setup. Does anyone here think those new Ring tweeters from Vifa would make great replacements? I have a pair of Lsi 15's and I love those new tweets I think they are way cleaner and image much better than the SL3000’s. It would be expensive, but worth the conversion. Any opinions?
