Not sure I understand why you mentioned the "Geez." My comments were not really targeting the M60s. I was inferring that the smaller Sony sub could not play 'cleanly' at levels that matched the M60s for the room size. Not if you needed any significant volume anyway. It's just a 10" HTIB sub. It sounded decent in my old cottage when I sat 6' from it but it wasn't made for the space I tried it in above.
To answer though, I think they are ver. 2.
With great power comes Awesome irresponsibility.
