Thank you for the quick reply. So I don't drive them hard per se only to demo them when people come over. When I first got them they were the best sounding speakers I ever heard. Literally sounded like performance in my living room, now drastically sound different. I'm was assuming it's age, I believe they're from 2008. But for such expensive speaker I figured they would last longer than 20 years. I still have a pair of Klipsch and a pair of Advents that were made in the 70s.. Do you know if there's anything that can be done besides buying new panels? I vacuum them on a regular basis and don’t smoke. By the way absolutely love all the custom work in that studio was that your home it's beautiful absolutely envy the fact you have a place to walk behind your system I spent countless hours using a mirror and a flashlight to plug it unplug audio equipment lol.
