Which setting do you all use?

The 340s are supposed to go down only to 55Hz, so what happens if the receiver sends it frequencies under its 55Hz floor? Is there something in the speaker which will automatically block out those under-55Hz frequencies, or will they just cause distortion?

Right now I have my front 340s (L/C/R) set on "small" with the receiver's crossover at 80Hz (its lowest setting), and the subwoofer set in "LFE" mode which if I understand correctly means that its internal crossover is not used, it simply reproduces whatever the receiver feeds it.

According to this article, if you have anything other than tiny satellites, having your speakers on "large" will make the subwoofer blend in more:

What's everyone's experience been with these kinds of settings?
