12" ported box design

I ordered the dual 12 " ported box design and the plans came thru fast and seem very easy to understand. I haven't got to build it yet but from the looks of the instructions I believe it will be easy and the box will come out amazing. I love CT Sounds

I'm an idiot

The drill slipped and I punched a whole in the rubber surround. So once I replace it I'll let you know how I like them....
