If you prefer to have towers,
Fluance has three options in your price range. The Fluance Elite 5.1 package is $730, Reference package for $1190 or step up to the Fluance Signature package for $1480. The Signature towers were reviewed on Audioholics and were a recommendation at that price range.
Paradigm is another reputable brand and they have the
Monitor SE Line if you want front towers, or the
Cinema series package if you want to wall mount the speakers. (They can sit on small stands or be mounted with brackets that allow tilting. See the Downloads section for the manual to see the installation options.) The Monitor line is a little over budget. For the 3000F towers, Atom surrounds and 2000C center you're looking $1470 plus a subwoofer and receiver. Some other options as well if none of those float your boat.
