swan divas 5.1

I was recently in a pawn shop and ran across a pair Swans Divas 5.1 that appeared to be in great condition. I never heard these speakers, nor do I know anything about them. I placed them on hold until I could find out some info on them. I would like to use them in a 2 channel setup with my tube equipment. If anyone out there know anything about these speakers,please help me out.I guess some of the question I want to ask is, How accurate are they, and if hey would be ok for the type application i want to use them for?
