An M60 in the center would probably sound spectacular, but would definitely be too tall. The screen should be placed such that the bottom one-third is below eye level. That only gives about two feet below the screen to play with.

An M22 would fit, but I don't see any benefit to using one over a VP150 (except saving a few $).
