Hello all:
Here is a look at my almost finished dual subwoofer project that I have been working on this summer. I learned a lot, made a bunch of mistakes that I tried to correct to best of my abilities but I truly like the finished product. I see imperfections everywhere but that is the curse of DIY... we are the worst critics of our own work.
I definitely could have gone a less expensive route by buying one of those PE Sub kits but education is not free
. I have parts for one more sub but most likely completion of the 3rd sub will have to wait until next summer as the rainy/cold season is upon me in PDX and waiting for paint/poly to dry takes 2x what it did over the summer.
Regards,

Description: DIY 12” sub with 15” passive radiator powered by 500W (max) plate amp. Constructed from ¾” MDF veneered with quilted Bubinga treated with Tung oil and then covered with gloss polyurethane. Dimensions: 18” high x 18” wide x 19.5” deep and weighing in at 71 lbs each. :eek:
Subwoofer: http://www.parts-express.com/pe/show...TOKEN=29411315. The version I have is the old AudioPulse buy-out that PE had for sale at $199.00 prior to TC Sounds making a come-back and offering the same driver for $20 less :(
Passive Radiator: 15” passive radiator with mass disc set from DIYCable: http://www.diycable.com/main/product...roducts_id=685. I got these when they were a sale for $55 a pop (not bad).
Amplifier: 500W Bash® from O Audio: http://oaudio.com/500W_SUBAMP.html. Very high quality offering with features most other 500W plate amps do not have.
Wood veneer: raw Quilted Bubinga from Veneer Supplies http://www.veneersupplies.com/catego...%84Figured%29/ attached to MDF using Better Bond Heat-LockTM http://www.veneersupplies.com/produc...neer-Glue.html and regular clothes iron. Veneer was treated with pure Tung oil and then finished with oil based gloss polyurethane. I initially wanted a French polish using super Tiger-Blonde shellac but the labor involved was simply too much for 8 faces. ;)
Cabinet feet from Dayton Audio: http://www.parts-express.com/pe/show...number=240-717
All cabinet corners wrapped in Aluminum 6063 corners from Speedy Metals: https://www.speedymetals.com/c-8345-6063.aspx painted matte black with latex paint and finished with oil based gloss polyurethane.
12 gauge internal wiring from amp to sub.
Tuning in progress (initially added 700g to each passive radiator). First test run was impressive.
Cabinet construction: ¾” MDF all around. Sub and passive faces are 1.5” MDF. Cabinet joints are 45 degree corners joined with Gorilla GlueTM wood glue and biscuit joints (2 per corner).
