Don't know why I've never thought about this before.
Regarding this article
about center channel speaker placement...
If using two center channel speakers would there be any issues of placing them directly to the sides of the TV/Screen inside of the front mains instead of above and below, providing you have adequate room? Seems like a couple of M80's placed in this manner along with the pair of my existing M80 fronts would provide the perfect sound stage and imaging.
What do you all think?
Edited to add ... What about using a pair of M60s for the centers in the side placed manner along with the pair of 80s for the two front mains? Would they match?
