Yes. I suppose "old" is accurate in that they have been around for quite a while, but they can still be purchased brand-new from The Audio Insider and OZ Home Theater.
I said old because I had the Swan Divas 10-15 years ago!
While I have never directly compared the 6.1's to the SongTowers, I can say pretty confidently that the SongTowers will be better in every way - including how they look!
I still own a pair of the Swan R1's that I use for surround sound and when compared directly with the SongTowers for surround duty, the ST's are orders of magnitude clearer, sound more accurate, and are more tonally correct - the Swans sound muffled and flat in the midrange and the top end sounds strident and artificial.
