center speaker veritical?

[LOA5000]

I was reading on the internet that its better to setup your center speaker vertical instead of horizontal. Would this be true with the pc351 infinity primus center speaker?

No. THe PC351 is intended to be horizontal. If you use it vertically, there may be some deconstructive interference. The tweeter will be farther away from you (depending on whether you have it facing in or out) causing peaks and dips at some frequencies, and lobing will occur horizontally.
