Both speakers, in their entity need to be replaced at no cost to you. The old ones collected at the dealer's expense. The dealer needs to refund to you 15% of the price of the speakers as an accommodation for your lost time and money. Nothing else would be fair.
What would you do?
I just received a pair of speakers that I have been waiting 6 months for delivery on. One of the mid drivers cone is dented probably because the manufacturer forgot to put plastic protectors they normally use to avoid these issues. My dealer offered to come to my house and replace the mid drivers in both speakers. Is this acceptable? Should I get a new pair of speakers? They cost me $50,000.00.
