Riker,

I think it mostly has to do with your music vs home theatre preferences. With a 2-sub system you will not notice the lack of full range out of the center as much. My main concern was for listening to multi-channel music without a sub. I am speaking theoretically however, as I do not have all the speakers to reconfigure and play around with like a lot of other members of this forum so Im sure they will chime in as well.
