If those speakers are more efficient than the others it can lead you to believe they are better, when the reality is they are simply louder. You are also talking $400 each, so there is, in reality, stiff competion such as:

ACI Emerald
Odyssey Epiphany
nOrh Classic 6.1
VMPS QSO 626
Axiom M60ti
GR Research AV-1

Of course, that isn't even touching those speakers available from Paradigm, PSB, Def Tech, Boston Acoustics, B&W, Dynaudio, Mirage, Monitor Audio, etc. If I were to spend $800 in one shot I'd look around before purchasing.
