I would take a look at the NHT Absolute Tower, it's not a full-sized tower and measures incredibly well. Also take a look at the Goldenear Triton 7 Tower, these speakers sound excellent and I am strongly considering them if I upgrade.
I'd also recommend looking at a nice pair of bookshelves instead of towers. For a tad more money you could get a pair of the Ascend Sierra-2 bookshelves which are incredible sounding. They were just released and succeed the very popular Sierra-1 bookshelves. Since you will be adding a sub, the lower extension of towers compared to bookshelves is wasted and the end result is essentially the same sound. Difference being $1350 buys you a better bookshelf than it does a tower.
