I just finished my first sub and wanted to show it off a bit. My brother just had a kid so he's had to shelf his desire for a new home theater. Since his birthday is coming up, I figured I'd make him a sub to get started on. After calling him up and telling him my idea we came up with the following constraints:

$150 budget (total, not just driver and amp)
Had to fit behind the tv

The design I settled on is a ported enclosure in an LLT configuration using Dayton's 12" shielded subwoofer (near a TV remember) and the Daton 70 watt amp (yes, only 70 watts). With a volume of 125 liters and tuned to 26 Hertz, this design has an F3 of 25 Hertz (in theory and after testing). This is the smallest sonosub I've ever seen! Best of all, the total costs for everything (including the spray paint) was under $130.

I've been breaking it in in my office. I like it so much (and will miss it when it goes) - I may need to build another sub!

Note: The graph I posted is the theoretical performance (blue) and the near field measurements I took (red). The massive peaks and dips in the red is no doubt from room effects. I'm still trying to figure out how to tame my office / listening room.
