I've tried a couple of DIY subwoofer projects, both of which turned out to be dismal failures. (one was a large transmission line design, the other was dual 300 liter sonosubs tuned to 15Hz)

I'm not sure if the problem was the drivers, amp, methodology etc, but I didn't have the time, cash, or will to swap things around to improve the sound.
I am, however, still interested in making a monster sub. I've got a pretty full woodshop, and decent skill to get the job done. I've been considering the purchase of the elemental designs A7-900. It's ranked #1 on the craigsub list, and I've heard alot of the subs on that list and agree with his opinions.
This sub is interesting becouse they make it very clear the exact drivers and amp they're using, and the tuning frequency. I'd probly use a pair of 6" ports or a trio of 4" ports instead of slot porting, but other than that it seems pretty cut-and-dry.
Anyone with any comments or suggestions on building this sub? I have no problems making it monsterously large, but don't want to make mistakes with the port lenths and configurations etc...
Heres a couple more links to the sub:
