regards the 125 hz roll over point.
Are you setting this in the head unit or through a filter in the sub itself ?
I would start with finding the sound curve of both drive units and tailoring it from that.
If it is in the head then it will depend on the range of the focal vs the sub + if the sub is self/alternatively powered.
If it is separate powered I would be inclined to let it have more range and let the focal drive the lower/upper mid more closely.
The Focal are a good size and power so can go deep I would imagine?
I set my sub to come in lower (100hz) simply because I used to listen to drum'n'bass so it had a lot of bass and I wanted to let it work on the low notes.
More general music seems better if you bring the Sub in higher and let the other units focus higher up.
May I ask where you got the head unit from for that price? It looks like a very nice unit.
Also if you want to give the head unit more power support it might be worth putting one of the power supply smoothing capacitors in line with the power feed, These give it a great reservoir but more transient performance for the inbuilt amp. It's not worth going up to the maxpower sizes but I did have one put on the head unit of my Volvo and it made the mid-range a lot better and more clear generally.
Oh and dynamat is lovely even if it costs a fortune! Had a good play with the settings while having CD and Bluetooth music from my iPhone playing and have set the filters at 100hertz It seemed to give a bit more mid range clarity and oomph Messed with the slopes and EQ as well and went with the ‘Vocal’ eq setting and set some shallower slopes around the cutoff points Just slightly reduced the gain on the sub as well to about 50%

I have absolutely no experience with subwoofers, neither in the car nor at home. But I could imagine that there's another plus point if you can lower the crossover frequency to 100 Hz. I suppose, but I could be wrong here, that the pitch is more clearly identifiable from the focal in the upper bass range than from the subwoofer. Some subwoofers tend to have an - albeit strong - foundation, but a bit of a one-note bass effect. If the Focal runs down to 100 Hz, then this is the octave from the low G on the double bass, although not the low E, but still. This way the Focal as an overtone from the low bass notes can improve the identification of even those bass notes that it doesn't transmit itself.
