I did a quick off axis check during the movie but to be fair I wanted to have the speakers in exactly the same spot(not angle), so I did not post it. The VP150 dropped 2 db and the VP100 dropped near 4 to the same place.. Just remember the VP100 was about 8 inches farther away to that spot making it a few more degrees off. It was quite alarming to notice how thin they both sounded off axis as I never really paid attention before, as I usually am not the one off axis.
For those interested, I did try both on at the same time
and as with my M82(M60/M22) combo, the center channel came alive as never before. It had a warmth/bass to it and yet still clear enough to hear the softer voices. I am still working on which is better VP150 above or below, it's looking like below on the first couple of tests.
I was thinking about trying the M22s as a center and not just one, 2 as well, vertically and then horizontally like the VP series, more on this center channel shoot out to come....
