I just got some and they sound great. Better than great, in fact, fantastic.I was wondering though, as I don't think they've ever been serviced, does anyone have any rough ideas as to how long the speakers last at their best? Is there a recommended time after which to get them looked at?
thanks,

Thanks for all your replies.In my haste to hear the speakers, I didn't actually look at any of the paperwork. Last night, whilst sitting in front of them enjoying some tremendous sounds, I looked through and found a service receipt from Quad dated from 2002, when 2 panels, some capacitors, and the dust covers were all replaced! I can detect absolutely no untoward noises from them with my ear next to them, and there are no buzzes or rattles at volume, so it looks like I'm good for a few years yet with any luck.
Thanks again,
If your units are not making any noise, even with your ear pressed against the speaker, and they will hit about 95dB without shut-down, then they are in good shape for the age. Loose dust covers will make some noise under heavy drive, but dust covers can be easily retensioned.If you plan on keeping the speakers in the long-term I would recommend that you have them looked at by a qualified tech. Unlike the original ESL, the ESL63 does not age well. 15-20 years if very well manintained, but typically much less. Probably closer to 10-15 years at best.
A good inspection will give you an idea of the life left in the speakers and what it will cost to bring them back to original spec. when the time comes.
and I'm sure the guys who work on them more than I will be chiming in soon.These panels will generally last about 15-20 years, if the set I have are any point of reference. They're about 20 years old - according to QS&D who checked my serial numbers. This will vary with the environment they lived in. Higher humidity will certainly take its toll, for instance. Not keeping the dust covers sealed or rather dusty environments will shorten their life. Consistent overdriving them will cause more arcing.
Mine did the sizzling/arcing when I received them and I knew what I was getting into at the time. I've elected to replace all the panels with new ones - not cheap!
I'd also check with QS&D; they've been quite helpful with me.
Cheers,

I got mine some months ago and he helped a lot!
