These are smallish bookshelf speakers. All original including the Fane Tweeters. The bass units are, as seen below, B&W units. Very nice sounding, in fact excellent, well made, heavy. According to the information sheet from B&W these are the result of research developing the DM2 &DM4 speakers so must be later than those. Maybe B&W's answer to the LS3/5A? Apparently they are the first B&W speakers to use Kevlar cones.
