Are you only looking for a pair of towers or do you want to integrate a sub in with them?
I just purchased a pair of Swans, I opted for the smaller tower the DIVA 4.2, the are on sale currently for only $709 per pair and I am very surprised by the build and sound quality for the price. They also make two steps up in the 5.2 and the 6.2 that range up to about $1100 per pair. There is also the 6.1 which is the previous large tower. All have excellent reviews and I don't think you can beat what you get for the money.

AV123 and Axiom also seem to be very prefered speakers on the forum. Both will have some great options in your price range.
Enjoy the hunt.
