Sorry for the quality of the picture. The sub was not the original subject of the photo and so perspective is off and it was cropped out of larger picture.
Total investment in this sub is about $40 but it performs much better than one would expect for that dollar amount.
The "cabinet" is a mantle frame from a defective electric "fireplace" which I purchased for $5. I bought a $20ish buyout woofer from PE which had nearly ideal specs for the 5cu foot or so volume and sealed alignment. The grill cloth (not shown) was salvaged from a Wurlitzer electronic organ. Bracing and baffle plate were leftover scraps from the garage. A few bucks for caulk (sealing) and glue and salvaged sheetrock screws and the basic sub was complete. It is driven by a salvaged 120W plate amp slightly modified for better low end response.
Though I don't really have a measuring setup the output is solid down to the 20s and a 10Hz test tone was clearly felt without having to crank the power. Certainly isn't perfect but the value is pretty good I think.
One of the things I really like is that it is a very thin package that doesn't impinge on the floor space but has considerable volume.

One (unseen) speciality of these CB subwoofers is that the mdf cabinet walls are lined inside with heavy ceramic tiles to add mass and stiffness.
