Will a slot port work as well if I aimed it down? I am thinking of coming straight up the back of the box and along the top. So, one 90* bend but I would use PVC pipe to smooth the corners. Is that okay? I can reduce the height of the enclosure significantly this way which is what my buddy wants.

Oh yeah, I forgot to mention that he also shot down the sand idea, sorry. I'll try it myself some day but this is just going to be a well braced enclosure.

I've seen (somewhere) that something closer to a slot was actually better.

IMO its all down to how low friction the sidewalls of the port are and that IF there is any bend, that the bend is "gradual" rather than "abrupt". A "pure" 90 degree bend is horrible. A 90 degree bend that happens over a gradual arc should be OK. Remember, the port represents a "slug" of air mass that is in effect a driver diaphram without a motor (the mechanical compliance is essentially the structure of the pipe and any internal resistance it has). Effectivly that "slug" needs to be able to freely "pump" back and forth.

Bummer about the "sand".. sounds like another compromised design.
