Just a short update about my towers. After being on the phone with David and Dina last week and going through more tests the problem has corrected itself. I did check all the drivers and they were ok. Who knows what caused the problem. I could hear the difference right away after the problem went away. They sound absolutely great now. I thank David for all his suggestions and help. First class customer service for sure.
Thank you again, David and Dina.
