The 3.x models don't have a 1:1 ratio of top and bass, it is more like 2:3. But many of us like to elevate bass slightly above the mids so being set for 1:2 (top to bass) is useful.
In the 20.x the crossover is set lower so it is more like 1:1, still, the current demand is more on the bass so even there I would like a stronger amp on the bass.
On my tympani in its original form I could just about make it with a 200 WPC @4 ohm amp for the top. The previous amp had less power into 4 ohms and would run out of steam routinely.
In my current variation on the Tympani, the mids are a 96 db sensitive array of Neo8 drivers. I can power the mids with 30 watts triode but for large scale music I still go back to ultralinear at 60 watts. The XO is at 250hz or 300 hz. That is by no means the actual halfway point in the large scale music I listen to. I believe that for most big classical and rock you need the bass to be well more than the theoretical breakeven would imply. I ended up with a pro amp with 2kw/ch into 4ohms. Under unusual circumstances I even clipped that.
So even if the stats indicate you would need a similar power on top as the bass, the bass will fare better with an order of magnitude more power. A 1kw Emotiva monoblock (4ohms) is not that much overkill. a 100W tube amp for the top is a good beginning.
