Class A or Tube (or else?) for high pass (bi amp) of Infinity Quantum 2

I want to drive the (difficult Watkins design) bass of my Quantum 2 with a dedicated "brute" amp (have a Behring EP2500 and QSC702 reserved), active crossover (4x4 miniDSP HD). The passive OEM crossover states 200/600/4k. 

Free of the high power requirements for the high pass (how much power DO the 3 Emits highs, 2 dome mid/highs and 1 cone low/mid need???) I would like to use a sweet amp, maybe class A or even tube? 

LOW BUDGET is a must. 

Any ideas, suggestions comments.

Accordign to the factory published diagram, tweeters are all the same. There may be a version for the 3+1 (rear firing EMIT). 

I would try with active 2 way signal split first (not sure what to do with the 'internal' 2 way paths for the bass). But can ALWAYS just run passive 2 way (some versions of the Quantum 2 HAVE already binding posts for passive 2, and I am rebuilding the crossovers to factory spec for that reason).
