To get the best sound out of speakers they need to aim at you. Most of the angled speakers like the Speakercraft AIM only angle to ~15 degrees, which means they are still pointing mostly down and not at the listeners. Look for speakers that angle 30 degree or more. The Deftechs should work. Some other brands to consider.
Paradigm 30 degrees - Various models starting at $279
Triad 35-45 degrees - Various models starting at $600
Episode 700 series 45 degrees - $799
Thiel Powerpoint (on-ceiling) 60 degrees - $1499
JBL LS360 30 degree - $549
There are probably others I'm not thinking about, but I wouldn't use LCR speakers with only 15 degrees unless you are sitting 3 feet from them.
