I was also concerned about this, and it seemed to spell out the same to me - cutting corners, but ultimately in the end I got a C5 .v2, S2's .v2 for surround. I didn't want to buy a set of S8's used with no warranty, and I also shivered in my boots thinking about what the shipping co's would do to a big heavy tower like that, so I ordered them new from my dealer for my own safety and to give him some business, and all he could get was the .v3's.
I am extremely pleased with the .v3's - which are supposed to have more excursion output from not having air leaking past the phase plug on high excursion - which must be really really loud and likely in full range 2 channel use only, cause I don't see those drivers moving anywhere near something I would consider becoming a problem.
I guess I'll have to keep putting them to the test to see how thing go in the super ultra high SPL's to see if they explode
Otherwise, we EQ'd and setup all my 4 non equidistant subs again last night and ran some full range sweeps and this is how my results look in room.
This is without ARC running and before doing any room correction at all... Very very happy with the sound in there.
