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?

• photos from each side
• any scratches
• look out for details on the photo, is it surrounded by a well cared for system, or on a bench outside?
• original packaging
• what amp it was used with
• seller's communication - eager, strangely too eager, normal, reluctant, etc...
• seller's background - when it's craigslist, or something iffy, definitely look them up e.g. linkedin

If the seller is dishonest, he’s not going to reveal any problems such as a rubbing voice coil or if something is not original, such as a driver that was replaced with a non-original driver. Personally, I’d never buy a used speaker and if you are your main concern should be their refund policy/ warranty and if the seller would be required to pay for the return shipping. To me buying a used set of speakers is not unlike buying a used car and buying someone’s else’s problem. Many speakers also get abused and cranked up and from day one without properly breaking them in and that will also lessen their life expectancy!
