A lot of good advice given above; the rare thread that, so far, does not include crazy accusations about other comments/commentators.
I have not heard any bad comments about ProAc speakers going bad, and I've seen a few older models that are in good working order, so I would guess that they are not particularly prone to early senility.
Speakers age at vastly different rates so there is no handy guide as to how long to expect any given speaker to last--it depends on design, materials, and environment. I have a local dealer that makes custom speakers out of mostly vintage parts, some of which are extremely old. Most of the woofers are from the 1940's through 1980's, and compression drivers can be much older than that. In my own system, I run a compression mid-range driver that is just a bit over 80 years old.
