I’m of the view that sats + subs is not optimal unless the monitors are also being crossed over before the amps (not just the subs).
Otherwise, you’re not getting the full benefit of reducing load/distortion on your mains (they’re still being asked to move/do excursion below the sub XO frequency).
In which case, given you said you have the room, I’d go for towers for more sensitivity, greater power handling, and more bass for the same footprint / outlay.
One option I’d totally recommend is ATC SCM40A (active version!). You’ll get superb midrange, and they’re easy to place cause they’re sealed boxes. There’s also a bunch of technical reasons why active biamping is superior. They’re not cheap; but you could recoup that somewhat by no longer needing to passive bi-amp (i.e. sell your current amps; and no need for stands).
A true 3-way like this will walk all over something like the Nola Boxer. I've heard the Boxers and like them, btw, just not the same class of speaker, and I'd go as far to say when you count the cost of a sub (or 2 subs), the cost of passive biamping, as well having, well, SPL limited 2-ways, you're not coming out ahead with small speakers at all.
