When using the compacts as a filler for the sides of the room is there any sort of phase cancellation I should be worried about.

Any time you have two identical (or very similar) sound sources with overlapping coverage areas, there is the possibility of Multiple Source Interference.
If you are using the L1 Compacts to fill in areas that are not covered by your main loudspeakers, then there's probably minimal overlap of the coverage areas. If you're getting significant overlap (and problems), then you probably didn't need the "filler for the sides of the room". The solution is to move the L1 Compacts or turn them down.
In portable sound applications, you can anticipate some problems but you may have to get out to the gig to experience them and deal with them on-the-fly.

@NAW-T-BOY, You may want to consider adding some time delay to the L1 Compacts based on how far away they are from the 812/F1Subs.
