Infinity Quantum 2 - crossover - tri amp

The brochure states

- 200 Hz for the Watkins woofer (dual coil, 2 paths in the XO), 12"

- 600 Hz for the 4" conde midbass 'transmission line loaded'

- 4 kHz for the 1.5" DOME midrange 

- above 4 kHz for the 3 Emit tweeters

The 600 Hz for the midbass seem odd. That represents (200-600 Hz) only 1.5 octaves for the 4" cone. And 600 Hz even for a larger (but still small) 1.5" dome tweeter is IMO very low. 

Can someone verify/confirm those brochure values? 

Also, what is the 2nd frequency of the Watkins woofer? One path is: 700 microF plus 4.3 mH in line. The the other path: 1100 micro F and 20 mH in line. 

Attempting to use digital crossover and 3 amps.

Already getting helpful tips from one reader on DIYaudio. 

I may just start with active bi amping, running the two Watkins coils in parellel and use DSP driven by big power amp (have class H and class D on hand), then the passive network for the midbass to EMITS with another amp (class A/B for now, may class A or tube in the future?).
