By them all and let us know which you like better.

I have tried my M22s as centers and they do sound better than the single VP150. So far as off axis goes with the M22s being on either side of the TV had some issues, as the nearest M22 was always louder, thus the sound was not centered.

The VP150 always has a centered sound to it but does measure 1.5 db lower about 20-25 deg. off axis, in my room, it is still clear, but does sound less loud when comparing direct to off axis.
