I need some help explaining how the sensitivity works with different subs. If it has a low number, it doesn't take a lot of power to make the bass. A higher number takes more power. Is this a correct statement? Or is it the opposite?

Opposite.  Higher sensitivity means higher SPL with the same power input and in the same enclosure.

And the same measurement technique, and the same motor topology......... sensitivity of subs -- posted image.

Sensitivity can be somewhat helpful, but isn't everything.

sensitivity of subs -- posted image. That's one of the things I love about you, Steven, you keep me honest.  I should have said "all else being equal"...

Oh, I was just trying to add to what you said and to further my point that sensitivity shouldn't be the only thing you look at.  Your post was just fine to answer his question.
