winisd and 12 volt are both cr@p because they both dont account in port displacement. They assume you will do that yourself which most people wont and when you do account that in, your airspace will be different and you will have to input in a different airspace which the calculator will give you a different port length and you'll do that over and over and never get a definitive number, its a never ending paradox. Thats why only google sketchup, autocad are the most accurate because its a full 3d model, followed up by xplicit audio ultimate car app's box calculator and then torres box calculator in that order. 12 volt, winisd and RE calculator has no place in the actual box dimensions and design.
I would just caulk the wire hole
I use the 12v to figure my port length and check it against winisd then I figure out my sub, port and bracing displacements, add those to the desired volume for the sub then play around with dimensions on the12v volume calc till I have the size I need to accommodate everything. Used this method for over 20 boxes. You have to know what you are doing but it's simple and effective for round port designs.
Do not!! Last several enclosures you made had slot ports //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Yeah... a lot do that don’t mind buying a port. No noise at all unless the ratio is jacked which can happen with a slot as well.
everyone. They are superior efficiency wise by far. Just harder to get proper amounts of port area since port area is set in stone with pvc sizes.

octo gets similar but is still inbetween slot and aero in terms of efficiency. aero is still king in terms of efficiency.
