Anyways this is only my second box and let me tell you.. For a novice to try this kind of box with little to no tools was stupid :p
I was bored one day and was looking at this box design from elemental designs. It was initially for a single 12 tuned to 27 hz.. Out of boredom I fired up WinISD and loaded my subs specs and used the speakers volume and port dimensions and it yielded a very flat curve thru out my desired freq response.
Anyways after about 6 hours from start to finish this box rocks.
Here is the specs
And here is my finished product..
I wish I took pictures when I was building cause for me, out of a scale of 1 to 10 this box was a 12
Anyways hindsight is 50/50
