QUAD ESL 57 - Help needed.
Hi everyone I hope you can help. I've been looking into updating my Quad ESL 57's. I got the service history from One Thing Audio. They were last fully serviced in June 2010. There has been some suggestion that the Bass panel might by down on output. To be brutally honest the 57's hardly get used and were bought on a whim. I originally intended moving to be a bigger house and then start using them. This never happened . So, as you all know I love to restore things and I have thought about replacing the bass and treble panels with the more efficient products from OTA, this would make an excellent project, however, I also just feel like sending them off and getting them fully overhauled. I'm at a loss to understand how the bass panels may be down on output considering they have hardly been used. Could anyone explain this phenomenon?
Thanks
