Yes the box would work, but I would advise against buying it. It's most likely tuned really high so you'll be missing out on the lower frequencies. Your best bet is to get a custom one built, or you can get a design and build one yourself. If worst comes to worst, go to Lowes or something and get them to cut out the wood and you'll just have to glue it together.
You'll be much happier with a custom ported box over that pre-fab one.
He's referring to this one I assume (might not be same site though)
