Parsimonium being a play on parsimonious, because I wanted to see just how little I could spend to make this subwoofer.
The plate amplifier is an AudioSource 100w model which I got on the Free Classifieds forum here from DanP for $50
The woofer is the Dayton DCS205-4 which I picked up as an open-box for $25 (part 88-295-200)
The enclosure is the 3/4" thick MDF PE knockdown box which is a 12" external cube (giving an inside volume of 10.5" x 10.5" x 10.5" = 0.67 cubic feet) $37.82
The port is a cheap tube coupled to one end of a precision port 2" flare which I had (I used the other flare end on another project)
Port is 2" ID x about 9" deep, which tunes the box to about 36 Hz
finished with grey veneer and then the method TomZ used in his Toni Table Radio: boiled linseed oil, then seal coat x2, then sanding, then shellac x a few coats.
Sounds pretty good for being so low cost.
total cost is $112.82 for above, plus the veneer, glue, screws, finish materials, and oh yeah, a ton of time! (but luckily, my labor is cheap!)
