One other difference is the F12 is -3dB at 14Hz anechoic whereas the L12 is -3dB at 18Hz. The F12 also has a bit more power and a different class of amp.
In a nutshell, the SQ differences should be minimal but if you want the premium amp controls and connections go for the F12. But if you have to choose between one F12 and a pair of L12s, go for the pair.
Loudness is not important for me, I listen at relative low sound level. Even my old Velodyne 1210 is plenty loud already. So the slightly lower power L12 is not an issue at all.
Between F12SE and F12, I'd choose the SE for extra $150 as it looks better. But L12 is so much cheaper. IF L12 sounds the same, only lower power, that would be my choice.
I am not into loud music, I am not into HT(had one, took it down, I hate the voice coming from the center speaker), I just watch tv shows at ordinary level. I don't want the sub to shake the room, I just want good base sound quality. Money is not an issue, but if L12 sounds the same but just lower power, it would be better as I can use my existing glass top for it as a coffee table.
Somehow, to me, a good stereo sound so much better than HT for tv. I still have a Kef Reference series center sitting on top of the tv collecting dust and the two rear speakers in the shed in the yard.
