What is ad copy like this supposed to mean?
"These speakers were bought brand new from authorized (speaker name) l vendor alittle over a year ago. They were opened for inspection and tested for performance. They have less than 2 minutes of usage and they are flawless."

the speakers are being sold at almost 50% less than retail. Why would someone buy speakers then "test them" for two minutes, then sell them a year later? What is a potential buyer supposed to think?
This type of thing happens more than you think.
People sometimes find "creative" ways of selling products and then sometimes this is where they end up.
Sometimes dealers go out of business and have unopened inventory that gets bought out by other parties whoc sell it here, etc.
If the seller has a good rating and you feel you can trust them, go for it.
If not find a local authorized dealer and try to negotiate a fair price.
Everything comes up here in sometimes mysterious ways.Got to call and talk to be sure.
The person may still be making money at 50% off. For example:
I bought four Canton 300CD speakers($1,000. each retail) new (NOT DEMO), from a dealer, for $350. each. Also three 360CD ($750. retail, for $200 retail, each) I didn't 'need' them, just at the price, I decided I could use them for a 5.1 system... maybe.
They are still worth, used, way more than I paid new. Deals like that come along. Folks buy stuff for cheap they do not want or need, with the 'possibility' that they will want it 'down the line'.
I found a Sony SCD333ES for $200 new.. I use it. Some have sold them for way more.. and I bet they paid what I paid.
I DO use my Cantons... those other people may decide to sell the items.
I think both cases are pretty common. Sometimes we just get to buying stuff on impulse and after it arrives check it for damage but never really integrate into the system and decide to resell when we get around to it. I did that with a fairly expensive MSB DAC. I never even checked it out and resold it with no problem. Also I sometimes think it's a way to sell a new item out of territory and but still make money on it.

Bingo! I once bought a pair of $1800 (retail) speakers from a dealer across the country. He had them listed as demos. When they showed up, the boxes had never been opened. I paid about $1200 for them, a good deal for me and of course he still made money.
Creative selling.

Saw this one a few months ago: New, only used for a few hours.

Emailed the seller and his reply was that because they were used less than 5 hours they were still considered new. I've heard of the 5 second rule; do we have a 5 hours rule in audio?

Many times dealers will sell product through AudiogoN. Some will even sell brand new product, but they cannot advertise it as such. So they try to imply that the product has been as lightly used as possible, just for advertising sake, they cannot list it as 'NEW'.

That makes a lot of sense John
Also agree with John, as a way to sell gear that the manufacturer 'forbids' selling on the 'Net.
i bought a $3000 preamp this way that was a year old and only opened to take the picture. come to find out it was a dealer who had one of his employees list it so he could sell it in other dealer's areas without getting them mad.
Yeah, John is right. The same thing happens with photo equipment such as expensive lenses. Dealers will open the box,and therefore cannot advertise as new, but your buying a otherwise new lens at a significant discount. You save, and the dealer still profits over his cost paid.
This is also a method of selling "gray market" equipment. That is, directly imported audio equipment which bypasses the authorized USA importer/distributor/retailer network. This method will usually violate any manufacturers warranty. Checking the serial numbers with the distributor or manufacturer will clarify whether the speakers were actually purchased from an authorized vendor. Most buyers don't bother to check because the "deal" could evaporate.
I have two amps right now that I bought two years ago. I opened them up to check that they worked properly. I then boxed them up immediately as I was in the process of moving to a new house. I'm in the new house now, have been here for two years, and I still haven't used these two amps. If I were to sell them, my ad would be just as the one you stated in the post and it would be absolutely true. If a potential purchaser was suspicious and chose not to believe me, then all that would happen is that they would lose out on a good deal.
People like myself sometimes have more dollars than sense. This happens all the time and you should take advantage of it as you will get a great pair of speakers. What a country!
A few dealers I know have 5 or 6 user names and sell all kinds of new or semi-used gear at much less than retail. They pay 5000, sell at 6500 and you pay 3500 less than purchasing the item from a regular dealer. They get to play with gear and make money. Ethical? Do they sign contracts? Who knows.

Manufacturers are always patrolling these pages looking for zip codes, names, etc. because they hate seeing their products undervalued. It's a common cat and mouse game across all industries of the internet.
