Do you know yet, what the FS is, for the 15's, when ordered with the 33% less stiff spider pack??
We haven't measured TS with the different spider packs but expect around 30hz.

There's no need to purchase the softer spider pack unless you are using a sealed or 4th order enclosure. You will have to shrink the box and lose some efficiency by doing so if you stay ported.

 
Not ethos.

Horn would be the most efficient. Ported would be efficient and easier.
