The H701 outputs
Front 1
Front 2
Rear
Center/selectable sub
Subwoofer

Run Front 1 as tweets, Front 2 as mids, Rear as midbass, Center as front bass with splitter, sub as sub.

Unless I'm missing something, this should work, although splitting the center channel won't let you time align between sides with the front bass, but who cares, it's firing low and prolly messing with the stage if you run it high enough for T/A to start mattering anyways, so cross it low.

Alternatively, simplify your life and get some better midbass, Peerless SLS 8s perhaps.
Something that can eliminate one voice will make life easier, but my suggestion above should work too.

I agree with dogstar eliminate one pair of the midbass drivers you shouldnt need em especially with all the equalization the 701 offers
