I use 6 identical speakers for my 6.1 system. I was laying the center on its side for esthetic purposes, but tried standing it up to hear the difference. There definitely was one. Tweeter dispersion patterns and all, I believe.
Only way to know is to try it out and see what works for you, your room and your speakers. I would certainly give it time in any position to see what you think. It's not really an A-B in 5 minutes type of test IMHO.
Enjoy,
Bob
