Does that Sony use the Scanspeak revelator as a mid? if so... nice!! The revelator is a very well accepted driver used in lots of hifi DIY speakers. You can also find measurements on zaph audio. (Fantastic Driver, beats Seas in all cases, but expensive).
I still dont buy the bipolar/dipolar thing. The image seems TOO big, perhaps its decent for home theatre, but not for music IMO. The orion is undergoing too many revisions for anyone to have any sort of trust in it. (They could have used better drivers too.) That said the active xover is nice!
Paradigm uses the ADP (dipolar) as surrounds for their speakers, they are a good sounding speaker but also a bit TOO big sounding IMO. Lots of people prefer to use the S2's over them because they are not dipolar and provide a razor sharp image.
The B&W 800 series are very well made, and are not metal like the revels. They also present a better waterfall plot, step response and cabinet. That said the frequency response is "voiced" and sounds very dry and boring (and not accurate to me).
The Revel Salon 2 has a better/more extended response, particularly in the lower freq. It still has a very nice cabinet, but not as good as the original Salons or the B&W. The step response is not as good as the B&W but I would still take these over the B&W.
All this said, Running these speakers full range has too much THD in the lower freq anyways. I would STILL cross these over with a sub around 60hz to keep THD down around .5%. Dont beleve me? Check here.

Just because all these speakers can run full range doesnt mean they will be clear at this freq, besides the cabinet resonance at this freq is too crazy especially at these levels.
The Paradigm Sub2 can produce disturbingly low THD at 20hz at high db but is just too pricey at around 8 grand. The current sub i've been investigating is the SVS PB ultra 13.
Its just too difficult to produce a clean low frequency without a sub.
All this said the B&W and Revel are fantastic "full range" speakers, also look at the Vandersteen 5A.
If you want the most accurate response possible almost to a flaw seriously look at the Paradigm S8. I dare you, google it.
For any SANE amount of cash, Get a older B&W 8xx series, Revel F52, S8 and a nice sub. Promise you wont be jealous of those overpriced floor standers. Integration is key though!
I hope my comments provided some new doors for you people. I always do see the same Revel/B&W debates all over here.
