Floorstanding speakers vs. Standmount speakers&sub

I`m just curious as to what your thoughts are on this topic. I know this has been debated before but I couldn`t find much out there on this. The reason I ask is I`m currently using PMC FB1i`s with an Esoteric AI-10 integrated amp and a Bryston BCD-1 cd player in a small to mid size room, 16x13x8 with an open staircase. The room is fully furnished and carpeted and the speakers must be place about a foot off the wall. I realize that standmounts will not go as low in the base extension but paired with a good sub could sound as good or better than some smaller floorstanding speakers. I`m looking for a wider soundstage /dispersion and a fuller sound . The bass and clarity is pretty good on the PMC`s. If you have any suggestions for good standmount & sub combos that may better the PMC FB1i`s or any other small floorstanders that may sound better with my situation please suggest some. I did demo Dynaudio Contour 1.4`s, they were nice sounding. Thanks in advance.
