I'm trying to design a box for a Obsidian Audio 15. I would like to do a bandpass box instead of a normal ported box. I've been trying to find info on the difference and usefulness of the two. The most info I've found is here:

Bandpass..... explained. (http://www.caraudio.com/forums/enclosure-design-construction-help/510330-bandpass-explained.html)

How do I know which one (4th or 6th) would be better suited for my sub?

In the link above, it says to use this equation to figure out which order to use:

Fs/Qes = EBP

It says EBP under 70 - 4th order, and EBP above 70 - 6th order. Is this a reliable method? Or is there some other way? (OA 15 came out to 50.xx)

I've been running numbers through WINISD and this is what I've got so far:

Also, how musical are these boxes? Is there a certain ratio for the chambers and tuning?

Any help is appreciated.

PS. Would be going in a Tahoe.
