You can get the box custom built to any way you like with MDF or fiberglass.
As for those subs, a sealed or ported enclosure (I think that's what your asking) will change the way the subs sound. It really depends on the type of sound you like. Sealed enclosures don't get as loud but have a tighter sound. Ported enclosures get louder but have boomier sound.
