What to ask when buying used speakers?

I am a lot more likely to buy a used component than speakers.    My last few speakers have been new , reason for that is my last pair of used speakers needed a part that took months to get...   the seller was kind enough to pursue the warranty but it took 4 or 5 months.     

The only used speaker in my experience that is a safe bet are speakers like Heresy, Forte, Cornwall....   if you have a problem they are easy and relatively cheap to fix.  

Best bet is a speaker that isn't too old and has a transferable warranty,  but not too many speakers have transferable warranty...     ATC is the only one I know of.  Maybe there are others?

@oddiofyl  you can always contact the vendor and ask if you they are willing to transfer the warranty

If the speaker works now odds are it'll work another 20, so do you trust a stranger with your money? There could be a damaged driver that's squawking outside of their hearing ability or it was a gradual thing they adjusted to and don't notice. 

Often the cost of shipping + paypal +  agon fees can cause a used product to cost as much as the new thing will cost if you spend some time talking cash with a shop owner.

I failed to mention: Even if the seller accepts a bad speaker back and pays the return shipping one way or both or if it is covered under the manufacturer’s warranty, let’s not forget the hassle, inconvenience and wasted time involved! Time is one commodity we can’t get back! Personally, my time is worth more than the savings, and who doesn't love the smell of fresh electronics 😉! My advice again- when it comes to speakers-buy new unless you’re buying from a friend or trusted source and have tested the speakers first.
