My experience with B&W is that they have great support. I blew my tweeter on my 802 years after the guarantee was up, and they just sent me another.
B&W 802 Matrix Series 3 tweeter replacement help?
I blew a tweeter from some high frequency feedback. -That is, I guess the tweeter is blown ; are there fuses in line with the tweeters by any chance? If not, can anyone recommend where to get a new tweeter and whether or not I can replace it myself? If so, if you could tell me the basics about getting the old one out, that would be greatly appreciated. Bought these in 1994 and have really loved them since. Thanks very much, oats
