Beside my kids and my bride, I don't have much I can be proud of... but I'm pretty proud of this earth-shaking fEARful 15/6 cab I just built in my basement.
It's loaded with an Eminence 3015LF neo and an ultra-efficient 6.5" 18Sound midrange. Total weight, 59 pounds. Approx cost, $650.
It started as a 5'x5' piece of baltic birch plywood. You can check out some build photos here:

Or you can build your own, thanks to Greenboy's great plans he provides free to us bass mooks, here:
fEARful™ enclosures for bass/drums/keys
these are the most articulate, bass-massive, and downright loud cabs you'll ever run into. Dozens (hundreds?) of savvy bass guys have given up on their commercial rigs after building and playing through one of Greenboy's DIY cabs.
All Hail Greenboy.
