I have spoken to Kevin in the past on 2 occasions and I had no problems with the man or his products. They do not answer emails promptly, I know that for a fact. In this particular case, I am going to say the problems with the finish did not occur at the showroom floor. I am going to guess these cabinets are made in China and the QC at AZ (if any) is lacking. If the entire production and testing is done in the PRC, then it would explain the defective tweeter as well. The manufacturer needs to replace the pair and Kevin should not be in the business of trying to defend the shoddy workmanship.
