Guidance on ported box

[ncochran]

So.. I scrapped my 4th order idea as I really don't have the room to do it right (I could do it, but not right lol)

Here is what I am looking at. I am getting conflicting numbers between bassbox pro 6, Re box, Torres, and WinIsd. I would post super detailed results but no one has time to read all that, and I am building tomorrow lol.

Main things I am concerned with here are net volume, and tuning. I don't know which program to trust right now lol.

My dims are 22H x 35W x 14D and my goal is to tune 30-32hz with around 12 inches of port per cube.

Torres shows those dims as 4.73 gross with a 12.5 x 3" port @ 31hz just shy of 12 inches per cube and 3.35 net after double baffle and bracing,

Re box shows a little more volume and a little higher tuning.

bassbox shows more volume with lower tuning and a horrible peaky curve lol.

Also, with bassbox I realize that a lot of the issues could be the data I entered for the subs, but they don't have Sundown in their database and I had to add it manually. Does anyone know of a way to import sundown's specs into the database? I put in what was available on the Sundown site, but some of the data it asked for wasn't there.

I would really appreciate it if anyone has time to take a shot at this. Build will be port up/subs up in a hatch. I am open to all recommendations!
