With the PSA sub I assume you were referring to the XS30?
The FV15 is an absolutely beast, so it probably has very similar output capabilities compared to those of the XS30. Each will have their own strengths and weakness, but overall you can probably expect them to perform comparably.
Co-located, a pair of E112's should come pretty close to either of those, but in the end I suspect they would fall a bit short in total output and extension. Sound quality wise the JL Audio's are easily the equal to virtually anything out there, and indeed are better than most. If you choose to place them in different locations -- in order to even out any nulls -- then they would have an advantage over the other two, but then you would lose the benefit of co-location (which is where you gain additional output potential).
