Do the front 3 have to be at the same height? I'm planning to wall mount my tv, and I'm not sure whether I will be able to stand mount the centre under the tv due to height restrictions.

If that is the case, can I stand mount the LR speakers and put the centre on a low console?
Will that work, or am I better off with a horizontally mounted VP150? Or can I place a regular M22 horizontally?

All this planning is driving me nuts. Thanks for the support so far guys.
