Not familiar with that brand but I'd do a single 12" over a pair of 8's if the install will allow it.
They might say "don't try this at home" but nothing about not trying it at your friend's house.
*Efficiency*

This is why I love my IB 15”. I technically get all 3. I say technically because I know that by going IB it’s actually a very large enclosure but if you think about the fact that with a 15” sub I only sacrifice about 7” of depth (the physical depth of the woofer) so I have my ENTIRE trunk, plus it’s crazy efficient (it can get stupid loud on only 400w), and it plays extremely low with ease, authority & balance.
I'm glad I threw this out there. I knew I would be getting some more techie stuff out of it. And by these posts, looks like you guys are having fun with it as well. I see Todd you are using an Fi sub, how do you like it. I'm considering using a XV3 for a build in my daughters' 4runner. I understand they are pretty good for SQ which is what I'm after with some boom to go along with it.
I’m not using Fi. I’m using a cheap PPI Phantom 15” in IB (infinite baffle).
I can model them in Bassbox Pro but generally a ported 10 will have more SPL at the tuning frequency than a sealed 12. I tried this once with a sealed Alpine SWS 12 vs a ported Alpine SWS 10 and the 10 was louder. If the box is built correctly and tuned low then a ported enclosure can have less distortion at higher SPL than a comparable sealed setup because the subwoofer cone moves less at fb and with cabin gain removed with a DSP cone control is even better.

I was thinking along those same lines, but had really no way to back it up as far as the modeling goes. Just the train of thought of what a sealed vs ported box can do, i.e how it changes the way a driver works if you will, I may have that wrong too...lol
