Well, I gotta say it makes me a bit suspicious if he's selling a bunch of these. It really all boils down to his explanation and if you can verify it, through something like paper work and an email/phone call to HSU.
Perhaps he could give you a serial number that you could check with HSU. ( the Axioms have some kind of bar code/serial # on the outside of the box and on the speaker itself. It's possible the HSU's do as well.)
If you can't get this kind of verification and still want to deal then definitely push for a better price. No warranty, No paper work ect. should be pretty good leverage for you.
One a side note I know HSU customer service is excellent like Axioms and I once saw a post on their forum where a fellow mentioned a friend had a vtf-2 that was sounding funny and there was some issue of the warranty due to purchase from an "unauthorized" source. Well, they were all over it, so I'd guess you'd have a good chance of working something out with HSU.
Good Luck and let us know how it goes, Mike
