scratch everything i previously said you can do one 6" at 10.49" or one 4" at 7.1" or 2 2" at 13" I'd go the one 6" route
Wow. This is way off.
First off, bracing is a good idea, but you certainly don't need a 2x4. I wouldn't bother bracing a 1cf box, but that's up to you. If you do, a 1" dowel rod will be plenty.
Secondly, a 10.5" x 6" aero will put you @ like 67hz. And unless you own a CRX and it's a straight burp box, this isn't a good tune. A single 6" Aero would need to be 55" long to get you to 33hz. Lol. One 4" aero would be perfect for your application but it's still going to need be 24" long to get you to 33hz. I don't like using tubes that long, besides the fact that it would never fit in a 1.2cf box. I would look at doing an "L" shaped slot port. Make it about 12 sq in of port and 22" long.
Completely throw out the 2" port idea. Aeros aren't that great for small boxes in my experience because they end up being too long. I had this same problem a few days ago when I put together a little box for a single 12. I wanted to use Aeros I had laying around, but the lengths just don't work out well. Any decent street tune in smaller boxes is going to be 20"+ and that kind of length is just a headache.
If you are dead set on using an Aero, you can probably get away with a single 3". It's not quite as much port area as I would like to see you use, but it's close. And a length of ~ 13.5" will get you to 33hz.
