I had owned both the LFM1-Plus & FV-12 (both at different times).
Out of these two, for movies they were comparable, but I do give the slight edge to FV-12. Amp was tuned lower and servo was set. The output on the FV12 has the slight edge and just was tight and cleaner. Output also showed from the sofa I sat on, which was about 13' away from the sub. Also since I owned the LFM1-Plus and did have it on the subdude, it still didn't sound as good. It was nice, but not as nice at the FV12.
Both cabinets are not appealing. The floor firing and option to close off a port on the Outlaw was nice. Too me they are nice for end tables, but who really wants these kind of subs very close (near field). Push this sub away and let it breath and travel to you!!
I like kisses blown to me (ever seen the scene on Superman when the lady blew Superman a kiss from a distance and he flew away further?
Right now I don't have either (sold them both). Once I get my new house built, I do plan on getting either 2- FV12's or maybe the Legends by Epik subs, but for some odd reason since I know I had much smiles with the FV12, why not just get them and be happy. Plus my back is tired of messing with 60+ lbs subs. I am not getting any younger..... at least thats what my lower-back is telling me.
