After many years in storage I retrieved my 10B's and set them up. One of the tweeters appears to be blown. I believe it is a sl1000. It has the metal plate, the clear dome, and the wires at a 45 degree angle. It is hard to tell but it looks like there is a small hole in the center of the tweeter dome.
How can I be sure the tweeter is the problem?
From reading the posts it looks like the tweeter is no longer made. What are the options for replacements?
