Thanks speakerdave and Ed for the input. I'll admit that using the S99 box and port size would make things much easier but if the LE14A will work better in a larger encloser, even in a small room, then that's the route I'll take.

If I'm starting from scratch, I would like to take this opportunity to learn how to size the enclosures for my particular woofers. This is something I have been thinking about for a couple of years but didn't have a clear goal untill now. I'm not expecting to be spoon fed information, but if someone could give me a basic outline of the steps needed to properly size the cabinets, it would be greatly appreciated.
