AUDAX speaker, with "special" sealed cabinet

[arcturus]

I bought myself a few "cheapish" Audax speaker drivers from my work. I'm planning to build a pair of speakers with these. The drivers are HP170M0 and TM025F1. Since the woofers have quite a high Q-values, sealed enclosure seems like the best option.

Instead of standard sealed box, I got interested in North Creek's MAPD enclosure type. I have an old double-bassreflex cabinet, which I once made just for testing out some junk drivers. That would be easy to convert into a MAPD box. As the author says:

with a driver with a Qts of 0.6 or above, this is the best way I have found to tune its low end, and with generally spectacular results. Try it!

But I wonder what's the difference between between similar sized sealed, or double-aperiodic boxes? Lower Qtc?

I ran a cross-over simulation with these two drivers. Simple -12dB/oct filters...

So, how should this idea to be rated?:

And the simulated response curve.
