With LFE + Main, there's more bass of course, but in my opinion it sounds a little boomy. I've read about the double bass from the LFE + Main and some say it's not good.
If you don't have a Revel of JL Fathom sub with the F52's, I wouldn't try the overlap. Do you have separate Movie and Music crossover settings in the Marantz? Or perhaps separate crossovers by source. I don't recall in that model if you can do that. Does that Marantz have Audyssey? That's always a good check to see what the room EQ is suggesting. If so, I'd run Audyssey.
If you don't have Audyssey, then you'll need to go with good old tools and tips. Sorry if you already posted some of these items:
1) Have you tested and set the phase of the sub?
2) Have you set the SPL level for the sub?
3) Do you have an option on the crossover slope for the sub in either 12db or 24db options?
4) Have you properly set sub placement?
If you've done all that, then try a crossover of about 40 hz and then 60hz. See which you like better. With the F52s, my gut tells me you will probably like a 60hz crossover for movies; but for music and stereo listening, you'll probably want to crossover down to about 35 or 40hz.
