On the center:
If your seating in the theater is inside the LFR's wider sweet spot then I'll 2nd Mojo's recommendation,
Unfortunately, most of our home theaters are designed for more than two or three seats.
In my case the virtual center was good for 3 max. When I tried 4 seats the image was marginal at best. Some material seemed center, when sitting at the far seats, and other material sounded fuzzy .., or even flipping from centered ok to fuzzy/center to fuzzy/side depending. It was a bit tiring as it took a mental toll as you were trying to keep the sound centered.
A real center would anchor the sound at the center for all seats ... even those far out of the sweat-spot. Because of this ...I will have a center.
To take it a bit further:
The same applies for the surround speakers. It's the reason we want move up .. 7.1, 9.1, 11.1 ... 22.1?
So, everyone in the room will hear a sound coming from the same place ... in other words we are relying less on imaging and more on point sources.
