One speaker I like in that price range:
Fluance Signature Towers. The measure well and they look nice too. Also I think they are very likely quite a bit more capable in bass frequencies than the other speakers you have mentioned, so if you are going without a sub, they are a great choice.
Something else you can do is just take a couple bookshelf speakers and a couple subwoofers and make some tower speakers by using the subs as bookshelf speaker stands. That will give you very powerful and highly controlled bass. One thing you can do for that is get a
Hsu Hybrid 2.1 package and ask them to throw in another VTF-1 subwoofer. Another good and slightly less expensive solution is to use the Hsu VTF-1 subs and a couple
Philharmonic AA speakers.
