Ok, so after playing with numbers and trying to get a better understanding of these things I think I am going to go with 2 RL-p15 (check it has p and I am talking about p

) and it's going to be still sealed. (can always build another box if I am unhappy) I still have to decide to go with 2 Ohms or 4 Ohms. The 2 Ohms version has a lower Fs and Qt, resulting in a system that is smaller with the same Qtc, but has a higher Fb. I was thinking about putting both of them in one box so it could be placed below my display, and projector screen when ever I get that.
I have borked my laptop with the speadsheet data on it it

I think I was thinking about putting the 2 Ohms in a box about 1.4x1.5x3 for 6.3 cubic feet of space inside. But I don't remember now. As some of the more advanced programs don't run on a mac I wasn't able to do the modeling for xmax and watts stuff.
Can I get any recommendations out there for a size?
Are there any benifits for putting the 2 in one box? I know with 2 separate boxes I can tweak the locations more. But I like the idea of just one.
There have to be some sealed box fans out there!
