My DIY sub is complete. This project took about 2 weekends to complete. Most of the materials I had lying around the garage. All total I have about $300.00 into it. Here are some of the build specs:
(1) 15 Dia. PVC pipe 24 long. Pipe has an I.D. of 14.50 and the walls are .375 thick.
(1) 2 x 4 x Ύ MDF
(2) 2x 4 x ½ MDF
(1) 3 Dia. Cardboard tube 16 long
(1) 10 Titanic MKIII Driver
(1) 190W SVS sub amp
(8) Slate pattern vinyl floor tiles from Home Depot
I used the ported.xls and Unibox.xls spreadsheets that are floating around this and other forums to do most of the design. The sub should be tuned to about 25Hz. if I used the programs correctly. I dont have a spl meter at this time so I havent run any scientific tests yet. I hope to get one shortly. This sub is a giant leap forward from the PSW202 I was using before.
