Center channel question?

Does anyone know if there is a practice of limiting the low frequency sent to the center channel from the mixing process? I ask because I see alot of high end center channel speakers that dont go down below 40 cycles, and these are sold in packages with up to 6 matching towers for home theater, so I started to wonder why sell 6 speakers that can dip to 20HZ or below and when it comes to the center make it so "light weight" compared to the others? Is this because material sent to the center typically does not require it? I know it is not because of size because some of these speakers are very large and can be fitted with any driver and cross-over of choice.
Please dont say it is because of the THX 80hz rule because these manufacture's would not be packaging 6 towers with full range performance in the system had that been the case. thanks

Chad- I believe that you are correct. Anything below that would be sent to the LFE channel (and the mains if you have selected "large" for speaker size.

Thanks swamp, what I meant to ask is if there is generally
material encoded on the center track that dips into the low cycles......40, 30, or even 20HZ, or is frequencies that low not even put on a DVD center track? Although I am smart enough to know it would be rare, would a scene with a large explosion have 20hz signals in all 3 fronts?

Personally I like bass coming from the center , suppose you are playing a 5.1 Audio disc and the singer has a deep voice ? . However most of the newer televisions , Plasma, DLP. LCD, etc have very thin "tops" , therefore it is becomming next to impossible to place any center channel speaker on top of your television.
