Went with the XFL 1522. Now tuning help please

[dnewell2004]

I decided on the XFL 15 Dual 2. In the past I never tuned anything just built a box close to spec and made it fit. Now I wanna try and tune this to 32ish instead of winging it. I have 42x22.5x what ever I need for height in the back of the van. Was thinking sub up, port back. Any help would be greatly appreciated.

in an open cab like that i've had great results with sub back port back.

that being said, that's just my experience.

I don't remember what amp you're using to power it, what's the rms rating at 1 ohm of it?

also, per American Bass's website this is one suggested enclosure (some of the other pros on here may be able to get you a more specific design):

SPL 1-15" Box Design

• Outer Dimensions 1" MDF
• Length 32"
• Height 18"
• Depth 17"
• Port Size
• Wide 3"
• Height 15"
• Depth 14"

Diamond D3 1000.1 its 1000rms 1ohm. I've considered both back but I figured I could build a cover for it if I needed to put something back there if it was sub up

should do nicely.  if youre lucky Joe X or Triticum will chime in with a really good design.  I know that i used ABs street pounder style box for 2 12" xfls, but i dont know how generic their single 15 box is and after plugging it in to Torres it gives you 3.53 cu ft net (before sub and bracing displacement which i can find nothing on the line about the sub displacement for an xfl), and tuned to 42hz.  for me that's simply too high.  im a mid 30s guy.  you wanting 32hz is gonna require someone with more knowledge than me to chime in ?

So here is a suggestion, power: to sub rated, amp subsonic filter to 28Hz, minimum port clearance 3", figure is just an assembly guide:
