Got a nice new box, I wanna keep it. It's 1.75 per with a huge port (will edit in actual port specs later)tuned to 28hz. All of the higher power handling subs I see need more space so I'm looking for a subs that can do well in this box. I'm upgrading from SA-12's and the budget can be pretty high since this won't happen soon. Just looking so I can save up, or start saving.

Xcons or zcons will work well in that box.

The brace will be enough won't it?

Yea it'll hold together.

I will keep that in mind.

I'm not really sure what kind of power you've got or what your budget is, but if I remember correctly the 12" IDMAX's are recommended to be ported @ 28 hz and 1.75 is perfect. I owned an IDMAX a few years back and they are VERY good subs. Just an idea.

Xcons or zcons will work well in that box.

Two good choices there.
