Authenticity of Speakers


Hi all,

This is my first post on the forum. I am in process of building a home theater. I found a guy on craigslist selling Klipsch R-28f speakers, $500 for a pair. How do I check the authenticity of the speakers. Have anybody come across fake Klipsch products? He says, he got those from Storage Locker auctions. Should I trust these speakers?

Thank you @viridian 
Yeah, that is true. He says, these are brand new and I convinced him yesterday to to $400 for a pair.

When you say that the price is high considering age and provenance, I checked Klipsch site, and these are not yet discontinued by Klipsch, first built in 2014. Do you think $400 for a pair is still not a good deal?
Don't be suckered in by what you think is a low price. Something smells fishy here, so proceed with extreme caution.

Thanks a lot @rlb61 and @viridian 
I will check-in for the sake, but will probably pass on as it looks like too good of a deal.

Thanks again.
