Entent Posted June 14, 2010 Report Share Posted June 14, 2010 Hi im building a box for 2 DC lvl 3 12's i got some help from J00bles on here for building a box J00bles told me to do the box 36w X 14t X 20d and if you make it out of 3/4 wood, then you're looking at 4.6 cubic feet of volume total.you could then make the port 6w X 12.5t X 25 1/8"d and you'll get tuning at 34hz. now im going to be building this box but im confused on one thing and thats the port im just wondering what i should build the port like This Or This is there a dirrence on makeing the port like pic 2? and if i wanted to make the box like pic 2 could i just make the sides any lenght i want as long as the port is 25 1/8" deep or is there a certain lenght i should do? thanks Subs: 2 Dual 4 DC lvl 3 12's in ported box 34hz tune wired to 1 ohm Hu: Eclipse 5425 Amp: Soundstream pcx1500d Link to comment Share on other sites More sharing options...
