What would you do?

Zd542 - there is still a question as to whether the dealer is authorized to make this repair, has the ability to make this repair, and can guarantee the results and can guarantee the warranty. The manufacturer can answer those questions. What do you do if 2 years from now another problem happens and the manufacturer refuses the warranty work because an unauthorized person worked on it. That probably will not happen with a reputable dealer, but i would check anyway. If the manufactures recommendation is to have the dealer do it, then I would go ahead with that. But I would contact the manufacturer for a recommendation on how to proceed. Sounds like the OP is going ahead with the dealer fix, which probably will work out fine. I personally would still call the manufacturer or distributor.

For that price the driver manufacturer, the head of operations and the CEO/President, should visit you personally, install the replacement drivers as matched pairs, sit with you and listen critically for several hours to make sure everything is well, and take you out to dinner before departing so that you will feel that you made the best choice.

I would not have the dealer involved in this.

I purchased a pair of speakers for about half the OP's. A few months after I got them the mid bass driver failed. They were to heavy to bring back but there technician said he would come out and replace it. Well time went on and one day when I was in the shop the technician saw me, said he was very busy, asked me if I new how to solder and handed me the driver. I though it was a bit strange at first but am happy that it was fixed without expense to me.
