The picture's not great, and it's a little hard to tell how large they are. I have no idea whether the black thing that sitting on top of the one on the floor is a subwoofer or what it is . . .
At that price, I couldn't say "no". Well, I guess I could have, but I didn't.
They're quite nice: the wood cabinets are in excellent condition, and they have the metal grills. They sound good; they're not going to replace my Vandersteens, and I really didn't need them (of course, here at AK, that would never be an acceptable excuse anyway . . .), but they're probably worth maybe $300, and I was curious to hear how they'd sound. So either I'll find a use for them, or somebody else will . . .
FWIW, I find the 810s a bit "heavier" sounding than the 710s relative to my taste. Not bad in any sense, though -- I am not sure that my sense of the two speakers isn't colored by the fact that I own a pair of the latter but not the former!
