I would say they would work fine in a sealed box instead of open baffle.
Open baffle may bring many other issues you might not want to deal with.

The sealed box would help to control low frequency extension (that you don't really need for a center channel).
A side effect of that would be clearer mids and highs.

70 to 14k will be plenty for a "Center Channel" speaker....unless you plan on multi-channel music listening.

I would say that if you wanted to open baffle these you would need a pretty substantial baffle and still need something to control the bottom end.
A home theater crossover at 150hz should do the trick just as well as a small sealed enclosure.

Are you going to do any fancy finish on the baffle or just painted?

You might be able to get by with a smaller baffle by using a rear chamber on the driver.
This small SEAS chamber should do nicely for your needs.
Just a little aquarium sealant and some screws should do the trick.
This approach would at least solve the acoustic "Short Circuit" you would run into from a small open baffle since there is no back wave to deal with.
Just lightly stuff the chamber and enjoy.

I would figure a baffle board that is based on the "Golden Ratio" (Look it Up).
Place the driver on a position on the baffle that also adheres to the Golden Ratio ( this will help to minimize high frequency diffraction.
Mount one of those chambers behind the one driver; seal it with aquarium sealant and use screws to hold it in place.
Chamfer or roundover the edges of the baffle as much as you can (a rasp works well).
Build some kind of "kick stand" for the back of the baffle to hold it up.
