Quick update, after 20mins of listening. Standing wave bass null still here

but that was somewhat expected. Incremental upgrade at best in all other aspects. As noted in other forums, they do need to be pushed loud for bass to present itself, what was 33-35 ()Wiim Ultra) loudness for solid bass on Focal is now 45-50 on MoFi. That, I really don't like, but I'm hoping to EQ that, RoomFit settings are left from Focal setup.
Definitely need to go with subs.
On the plus side, aesthetically they look way nicer that 2 black monolith coffins from Focal
