Outdoor Sump Pump Basin 12" Subwoofer
Hey guys, just finished a fun little project this weekend, an outdoor subwoofer built from a 22 gallon sump pump basin from the home depot. Easiest sub I've ever built and it sounds fantastic. Not to mention it was actually quite inexpensive as far as sub builds go. Check out the pics below and feel free to ask any questions if you'd like. For now I'll just post some quick specs but will be happy to write a more complete write-up if anyone's interested. It's not the prettiest thing in the world, but it's also not really meant to be seen. But it can certainly be heard! I haven't taken any measurements of it, but might try and do so. The real trick will be seeing how long this thing lasts against the elements. Time will tell I suppose.
