Wharfedale Atlantic 100's or B&W D100's?

Does anyone know anything about the Wharfedale Atlantic 100's or the B&W DM110's? I can't find any literature on them. Someone near me is selling them for $100, is that a good deal? Like to get the Diamond 9.1's, eventually, but these might be good for the mean time and eventually use them as rear speakers.

Any help greatly appreciated.
