Richard, do you monitor loud enough that the center speaker is sympathetically vibrating, thus 
moving even little air? I've noticed that this can and does happen at loud levels and it absolutely 
feels like amplified sound is coming out of the center speaker. OTOH, properly placed small monitors 
in a properly laid out room present a very large and strong center from the proper listening 
position if they're worth their salt, and I'd say your Mackie's are worth their salt and then some.
