How long can Magnepan speaker last?

I am asking in term of build quality when proper used (no overdriving or abusing them). How long could it last? I heard some stories about the glue is weakening over the years and as the warrantee seems relatively short (3 vs 5-10 years) so it a bit concern me.

I am about to get a used pair of 1.6 and wonder how long it will last with me without having to fix them.

For any Maggies owners, I would really appreciate if you could share experience of failed Maggies, how old were they when they failed and what seemed to be the problems?

Is 10 years too long to live for the Maggies? If so what would be the typical life of them, 5 years?

Sorry if I ask so many questions regarding this. It will be a big step up for me and I probably can't afford any upgrade for a while so I would like to make sure that I am going on the right track. The price of them may be a joke for many of us here, but it 's significant to me.

Thanks a lot,

Ake
