I had the same type of situation happen to me with a DIY speaker builder which turned into a fiasco here with no resolution that made me happy. So what I would do is let the dealer come to your house and replace the drivers with a contigency that if it does not look right or sound right to you then the company needs to replace the speakers.
It sounds like the company is at least listening to your concerns which is better than the sleeze ball situation I went through.
