It seems Elac Debut reference DBR62 is sold for 179euros in a german hi-fi shop.

It says it can be bought only in pair.
In white(with same buy pair restriction) costs 246,50.
It becomes more confusing, as a pair has a price of 498euros in the same e-shop:

My guess is that black pairof 179/unit is a returned pair with open boxes.
But I tried to translate every word of the page(as I don't speak german) and I did not find a remark that the product is used.
ps: if a german speaker has more clues can make post informing us
