So I have started my design for an MTM with the Aura NS3-193-8a and the Dayton ND20FB. Here is the crossover, modeled response, and impedence:

Measurements were from Zaphs site. I have not included BSC, as they will be mounted nearly flush to the wall on the one side, and approx 4" in front of a TV on the other. I have also not included the response from the box, as I'm not sure how to splice it in. Other assumptions: -1.0" offset on both woofers. The cabinet will be approx 128 in^3, with the 1000uf cap for passive assist as per Wolfs design. Is this still valid with the rest of the crossover?

Comments or concerns? I would really appreciate some feedback at this point.

Basically all the cap does is provide shelving to the Fc (freq of cutoff) It shouldn't really affect much else.
I say go for it, and report back!

Thanks for the feedback. I will let you all know once construction begins. Here is the planned cabinet design:
