Personally, I would not get the 7's. I find that they are too small to be floor standing units and their sensitivity is way too low. The 9's and 11's do way better in that regard not to mention sheer output. If you go for the 9's (I guess that's what I am recommending), go for it! get the 390! If you however stay with Titans or Minis, stay with the 290.
Hope it helps.
