i like ported boxes better but you can go with the sealed box. well you got almost 6^3 if you fill up the room. great for them 1.5 to 6 cu feet per sub.
Can't be loud then don't have it.

How about going down the middle... 38" wide 18" tall 16" deep with 1" MDF will give you about 4.5cf.(after displacement) From there you can fill to adjust your sound a bit more. For Boomier bass, fill with up to 4 lbs of polyfil (pillow stuffing) for more precise, punchy bass, fill with blocks of MDF until satisfied.
I also recommend after building the box that you take wood glue and coat the inside of the box with it (unless you are using 12 ply russian birch) This will seal the MDF pores and reduce the pressure bleed that MDF has, especially since you have 2 of them. This also raises the power tolerance of the subs too, so make sure your amp has enough kick to it.
