In his original post,
@mbl11428 said he wanted a 5.1 setup. His price goal is about $5k for all those speakers, and about $2.5k for the front pair.
I recommend the Salk SongTower II. At $2800/pair, they're a bit more than your stated goal. In my opinion, they're worth it.

In general, I'd also spend good money on the center channel speaker so that it does voices clearly (movie dialog) and closely blends with your front left & right speakers. The SongTower II is a fairly new model.
Call or email Jim Salk and ask if a center channel speaker is available for it. But I also recommend spending much less on rear channel speakers. For example, the
NHT SuperZero, at $250/pair, is excellent for rear channel duty.
Wait until after you hear those 5 speakers, set up properly in your home, before you decide on a sub woofer. Too often, many people call for "sub woofer overkill" as a cure all. Bass response really depends on your seating location, the speaker locations, as well as overall room dimensions. Learn what works and doesn't work in your room before spending money on a sub woofer.
$2800 + $250 leaves you with $1950 for a center speaker and sub woofer. Please note that I did not include shipping costs. Salk, NHT, as well as several good sub woofer makers, sell their speakers directly over the internet. You pay shipping costs, but not the substantial dealer markups.
