Posted October 2, 200915 yr What do you guys think of the design? Its for a DC lvl 4 12'' subHow would I factor in a kerfed port to the design???If the kerf is secured as an external portion of the port, will it affect tuning or require a change in design anywhere?Specs come to:-2 cubic feet before subs displacement-32.5hz tuning-36.25 sq inches of port area
October 2, 200915 yr Author bump, want to buy materials tomorrow.I probably wont do the kerfed idea, i've heard there is no 'audioable' difference, and this is NOT for competitions, just for daily driving so...Does the design look good to you guys?
October 2, 200915 yr All looks pretty good. The only think I would change would be making a 45 at the bend on the inner wall of the port. That way It would be an even width all the way through the port.

I agree that you can just forget the kerfed port. It will not really make a difference in sound. The one thing that I would recommend is the use of bracing. You should use some bracing for the walls of the enclosure. This will help to prevent any flexing of the material.
