I am an open book. Do you honesty "claim" that Quad's service interval is in any way similar to a cone speaker in their price range? Do you have custom businesses specializing in repair of other speaker brands? Infinity-specific re-coning specialists?Dimitri, I see you're relying on obfuscation once again, just point to the post where a quad owner compared their service interval to normal speakers and claimed similarity, simple really. You're just inventing quotes to suit your position.
We all know they're fragile and have a very finite service interval, we accept that.
My irritation is not with the speaker as such, but with the company's utter inability to make it into a reliable, sellable product, either through a reliability redesign or through a reparability redesign for 50 YEARS.
I switched to electromagnetic planars (Eminent Technology) for the same reason.I agree with much of what you say Dimitry but from what I've experienced all electrostatics just wear out faster than box/cone loudspeakers - Much as I love Martin Logans I wont be buying another second hand pair because they just haven't lasted in use and seem to be difficult and expensive to service in the UK. There are a pair standing in my warehouse right now, gathering dust - I wont be spending any more money on them. I'm very glad to have owned them but find Maggies much more robust in use.

All you have to do is disassemble the speaker and desolder/solder 256 wires.
I quoted Quad manual, which requires you to keep the speaker in a low humidity environment
Therefore, the source must be attacked and destroyed, in order to preserve the cult of the company.
Are you sure that NO ONE made this claim?You also said quad fans stated they required no more servicing than cone speakers.
No one made that claim.
You made it up.
I clearly stated quads need a lot of looking after.
People are different. It sounds like you mostly enjoyed boxing up large 50-60 lbs speakers and shipping them. It also sounds like ~$4k price tag for refurbishment is reasonable to you.I have some very early 989s that must now be about 20 years old.
I bought them for about £2K off a distinguished pfm grandee more than 10 years ago. They would have been £6K new IIRC.
They have been back to Quad twice for panel repairs. Well - one has been twice and the other one only once. Both after moving house, the first time (both) without the proper boxes. This (including postage and new boxes and packaging) cost about another £2K. And they now all have the new glue formulation.
If I have to shell out another £2K over the next 20 years to keep them going, £6K in total for world class loudspeakers for 30 years - £200 a year. Bargain.
If I'd bough them new then this would be £10K over 40 years. £250 a year.

Being an engineer, I found the overall mechanical design of the speaker to be quite incomprehensible. Really, just plain bad and very unfriendly from a user repair point of view.
The speakers should have been designed with the front section of the grille being removable and the panels replaceable with dummy-proof connectors.
1. Cartridge and stylii are user replaceable parts with the process taking 1/2 hour. This is NOT what home Quad repair is like.
About 30 seconds via Mr. Google:Push fit 2kv connectors, what the mouser code, I'm in.
I have taken 988s partially apart, when I modified the input connectors and did a cap bypass. I also learned that the correct way to work on the speaker is with the speaker securely in a fixture, upside down. My house does not permit to have a dedicated wood frame fixture to be built, in order to have the speakers safely positioned upside down.
This must be your living room? Fully adapted as the permanent Quad repair station? I spy a little oscilloscope, professional soldering station, some other cool equipment. Like I said, all owners should simply equip their living spaces like you did and they should be all set for owning Quads in any part of the world. So simple, I wish I figured it out sooner!So the only actual experience you have had with Quad ESL's is to remove the base panel, some 15 screws. Yet you claim intimate knowledge and engineering experience of the panel construction despite never having never done this.
You infer above that a special jig is required, yet it is not.
