You'll get better recommendations if you give us some more detials. Price range, use (HT/Music %), sub included, room size ect. Floor standing isn't necessarily better. Depends on your use among other things.
To give you a place to start, look into the Infinity Primus line. I had a complete set for my first HT that I replaced earlier this year. They are good speakers for the price and you can improve them with some modifications. I'd avoid their subs though. The subs are fairly "muddy" in my book.
