Box for single DC XL 15

[KenC210]

So I am going t build a bx for a DC XL 15. I am looking at a box 22x21x20. I am looking at the port being 3.5x13x26. Sub up port back. This will put me on a low side of the box volume so I am wondering how this setup up is for the XL. I will be powering the sub with an AQ 2200. Will this be fine for a single 15 with this amount of power.

Should be fine.
