Alright, I'm obviously making my own sub enclosure, as I love making my own stuff (pride, etc).
I was looking at Rockford-Fosgate's website and noticed that the recommended enclosure volume for a sealed box is 0.65 cubic feet.... but I did the math and used various programs I found online and I got a value of 3336.29 cubic inches (which is roughly 1.93 cubic feet). That's more than double the volume... I dunno about you, but that's a huge difference!
The only thing I can guess is that used a different value for Qtc... I was using the "default" .7, but in order for them to get their value, they must have used .96 as the value. (reversed and substituted some simple algebra to find this).
So then, my question is... should I use their recommended volume or the one I calculated out (again, various times with different methods, so my math is right)?

rockford knows their sub better than any calculator.

Alright, I'll sketch out design plans using my numbers and theirs, can't hurt.
Another quick question involving how to harness the sides of the box:
Yeah, which would be better assuming the front of the box is on the left side? I guess it's not a question about force, but rather vibration...
I'm not sure what your actually mean but I don't think it would make a difference in which way you screw the boards together. In the pic on the right just turn the arrow up and its the samething as on the left then. Get what I mean??

lol, true, here's a better image to explain (black represents the sub)
It won't make a major difference which way you screw them together. I don't think the rockfords are going to putting so much force that you have to be worried about that. If your really woried put braces on each corner.

ok the force is going to be in all directions so it really doesnt matter anyways because unless your using nails and some really powerful sub and amp they both will work fine. Me personally i use the first method on everything that is MDF and not fiberglass.

I don't think it matters either...
Where's Red anyway...?
Makes no difference. Just make sure you get some Liquid Nails and "liquid" nail the seems.
Once dried, I'd question which is stronger!
