I would also contact B&W. In the US they are in Boston. I have emailed them on occassion and gotten quick and thoughtful responses to questions.
B&W Help... tweeter problems!
I have a pair of B&W Silver Signature 30s and this is the second tweeter that has fried. Has anyone out there experienced any problems with the Silver Signatures? I don't think I have a problem with the amplifier (Jadis Defy 7) and I am very careful about not overdriving the speakers. I am starting to question whether the silver voice coils are up to the task. This is more of a pain than anything but a pair of speakers this expensive shouldn't be going through tweeters!
