A friend of mine picked up some POLK RTi150's the other day and found out that the seller had blown both of the tweeters in the towers. I know the tweeters are very difficult to find and also very expensive to replace and she doesn't want to spend that kind of money.
My question is has any one used a replacement 25.5mm (1") silk diaphragm dome Tweeters voice coil 8ohm from Ebay and if you would have any recommendations on a good replacement. I have seen a few options but would like to get one as close to the original as possible. Here is a sample of what I was looking at:
