Thanks to Mike P. for his generous offer Adire Audio Shiva 2, I have finally completed my subwoofer project. I am still unemployed but at least I have a home theater system to get away from my worries.
The design..
Downfiring sub with a 17" x 4" flared port (Parts Express).
Cabinet size, 21" cube inside dimensions, 4.6 cubic feet for thr final internal volume.
Amp, 250 [email protected] 4 ohm parts express amp (older model, #300-794)
The project has been delay for numerous reason, I wanted a built-in entertainment center but another project, replacing a non-functioning leach field, has top priority of course.
I want the design to somewhat match the craftsman style molding in our house which I build from MDF sheets. I rather proud of the crown molding which was built from scratch.
For the sub cabinet top piece, I used a 3/4" Roman Orge bit for the bottom lip. Next I used a 3/4" round over bit for the top lip. I used 3/4" MDF boards of course, very easy material for my router.
For the legs and side trim pieces, once again I used the 3/4" Roman Orge bit. Small blocks of wood were place inside the legs which support the cabinet.
The internal bracing was a bit of a mess, I just used what ever scraps I had and started to glue them in.
For the finish, I just put on about 4 coats of primer then sanded it down. The final coats was two spray cans of gloss white.
Finally, here is the final setup, the TV is a 50" Panasonic plasma...
