Blown Woofers in Matrix 802 S3

I'd bet, as well, that if you switch your right lower speaker driver it will blow again. I'm pretty sure its not your amp, though. I had the exact same speakers. I bought them new, when they were current. My best friend bought the same exact speaker because he liked mine. My friend that works in the audio store had the same exact speaker. The store I bought them from had 2 brand new pairs on display. (One pair in a 2 channel setup and the other and the other was in a theater.) Every single pair of speakers I just mentioned had the right lower driver go bad. To this day no one can figure out why they went bad.

I was able to come up with the most plausible theory as to what was going on. Understand, though, I may very well be wrong and that this is just my best guess. The only thing common to all 5 pairs of speakers, besides the fact that they were all the same exact model, was the demo music. We all used many of the same CD's. Either we each owned our own copy or we lent each other some albums. I figure that there was something on one of the CD's, like a certain note or sound comming from right channel, that the speaker just did not like. Maybe a crossover point or a weakness in some of the material. Your guess is as good as mine. That's the best I can come up with.

I know that you are going to ask me what CD's we were using. We never figured out which one it was (If it even was one of the CD's to begin with.) There were well over 50 CD's that we had all used. Also, it was a long time ago and I know I can't remember them all.

Sorry that I couldn't give you more info but maybe something I brought up can lead you in a direction that my friends and I overlooked.

Sorry, I forgot to put this in my post. The speakers are not marked left and right. So, yes, if you move the left speaker to the right, it should still blow the driver. Honestly, though, I can't remember if any of us actually tried it.

As far as warranty goes, the 802 s3 was discontunied in the mid to late 90's; probably 97-98. I doubt that B&W would warranty something that old.

As far as #1 goes, don't hold your breath. B&W's customer service is terrible when it comes to things like this. I moved a few years ago and brought along a pair of B&W speakers that I had for only 2-3 months. There was no local dealer in my new location, so I asked them if they could just send me the part (crossover)and I would install it myself. Offered to send them the old crossover, as well. Anytime B&W hears the words shipping or mail, they go nuts. To make a long story short, They were kind enough to sell me a new crossover at full list and I had to drive over 100 miles to pick it up at a dealer. They made it very clear that they were doing me a big favour.

Looking at your #2, I really don't think it was the amp. In order to consider the amp as the cause, It would have to be used on all 5 pairs of speakers. I know for a fact that there wasn't one amp that went on all 5 pairs. Even if it did, how do you explain the same thing happening David_doerfer's pair? For me, at least, 6 pairs with the exact same problem, is beyond chance. There is also one other thing to consider with regards to the amp being the source of the problem. The amps that were used with the 802's were also used with many other speakers with no problems. That's why I though it might be one of the demo CD's. Its the only I can think of.
