Budget Bass Box
DIY Audio Guy
12″ GRS Poly Cone in a Sealed Box
The goal of this project was to build the CHEAPEST subwoofer enclosure possible. The baffle is birch veneered MDF, stained with min wax poly shades. The rest is plywood, painted flat black with a layer of clear coat. It was made entirely out of scrap material left over from other projects plus a few cans of spray paint.

1.5 cuft sealed
Very simple design.
I used wood glue and brad nails for the everything but the baffle. The baffle was glued and clamped. This way there were no nail marks in the baffle.
Tips & Tricks:
I put a round over on everything expect the baffle. This gives the edges a clean look and it is still very easy to mask off the baffle for paint.
Sealed boxes are very easy. If you plan your cuts correctly you only need to set the table saw fence three times.
It sounds great for for a $23 driver in a scrap wood box. It is not going to blow the windows out of your car but this is an affordable way to round out the bottom end in a budget build. This would be an excellent sub for a 2.1 system in an office or a bedroom.
