Buying used: how old is too old?


All,

Considering buying some used speakers from a well established company, e.g., Wilson, Focal, B&W, etc.

Aside from obvious technology updates, do speakers have a shelf life? If so is this measured in overall life, or number of hours played?

I’ve read some reviews that some speakers can really improve with age, no doubt longevity is going to be influenced by speaker drivers. Perhaps paper breaks down before other materials—I don’t know.

Old flagships can be bought for a fraction of their original cost and less than new mid-level speakers. No break in needed! But maybe they would be broken down?

I’m sure there have been numerous threads on this topic, but I didn’t find much in my search and am also interested in any recent experience on the topic.

Would be really interested to hear thoughts, opinions, and experience with this.

Thanks!

Used speakers with sealed enclosures are less likely to have internal insect and/or rodent damage.    
Any of the brands you mention in the 4-5yr realm, even 10-15yr realm will be fine and can be had for decent $$$. As long as they weren’t abused or subject to some other nastiness you’ll be fine.
Bought a pair of MTX Blue Thunders in 1992, 10 inch woofers, still kicking ass all these years later. Purchased a pair of JBL 8 inch woofers at the same time, 10 years ago the JBL surrounds of butyl rubber were shot, they also featured reverse phase, ie. the positives markings were actually negative, a nine volt battery test confirmed the polarity. i now prefer the rolled edge woofers over foam. I have experimented with a variety of woofers from different manufacturers over the years. Cerwin Vega rolled edge, Kicker rubber, and MTX rubber have stood the test of time. I have a pair of EV 12 inch 2 way horn speakers that were born in the late 60’s and still sound good. The vinyl wrap is peeling, but the speakers still work well. Some speakers age well.
Highly subjective. Totally depends on the design, and selection of parts and especially the quality of manufacture.
Lest we not forget that longevity also depends upon the quality of care and maintenance. Sometimes, people are the worst enemy of how long something man made will last. 
I say these things because I have always been a careful and concerned caretaker of all things I purchase. And most especially my audio gear.
The exception, of course, pertains to audio equipment that contains predictable parts that will eventually reach end of life and will need to be replaced. The example being, vacuum tube replacement. I for one can live with that.
