I have a pair of M-Audio Studiophile BX8 monitors (NOT BX8a) that the Tweeters don't work no more. I talk to the parts service of M-Audio and they don't have that part availeble anymore. They send me a list of there oficial service centers to see if by any chance you still got that part in your stock but they dont. So now I have to find a replacement for it. The magnetic bobin (sorry if this isnt the term) is of 1 inch. Any idea what tweeter will work good on them? Thanks.
