One thing I didn't mention is the best spot for the sub is corner loaded, so I already have considerable boost there.
Along with being in a small room, I think I'll get some decent room gain.

I have virtually no experience with woodworking, so I think sticking with a simple box for now is smart for me. If I'm not happy with it I can move up to a ported enclosure at some point.

The worst scenario I can imagine is going through all the trouble of building a huge ported enclosure, and then having to EQ down the low end because there's too much gain, AND having a steeper rolloff.

I grabbed a crown XLS2502 for a great deal, so I'll have plenty of headroom to EQ up the low end, at least down to 20hz.

Great thread, I have just started down this DIY road and had a very similar thought process on building a new sub (or two) for my HT room. Let me know how this works out for you.
