Just wanted to show my new box. It's not all the way done, still have to bolt in the threaded rod and run the speaker wire. Yeah I know, I got sloppy with the paint, oh well. 4.4 cubes before displacement and about 4.2 afterwards, tuned to around 35 hz. Tuning will be dropped if I'm not happy with it.
Here you go

im wondering the advangages if an external aeroport setup?

i know its easier to change the tuning, but does it sound different?

Increases spl because there's less turbulance inside of the box.

if they are precision ports...im sure he screwed them in and sealed them up with sealant.

There's actually a piece of sheet metal inside, and the ports are screwed to the sheet metal instead of the mdf, it holds much better that way. There is weather stripping underneath of the port lip to help seal. There's also duct tape around the ports on the inside to make them smoother and seal it better. I'll show the internal pics when I'm done.:)

WOW you went overboard on mounting the ports! Silicon around the mounting lip and screws are more than enough. I had to take the ports out of my old boxes many times and after you unscrew it, you still have to silicon to deal with and it was a B*TCH to get off. It's very strong, took some MDF off of the box when I was pulling them out.

And no, externals don't sound different than internals, at least to my ears.

Yeah I'm hoping that it gets loud. I'm shooting for atleast a 145+ with this as my daily box. My spl box will be a bit different.

maybe external ports are just for people too lazy to figure out port displacement

Okay here is the late updates. Yes, it's been in my truck for awhile, and yes I'm lazy. I'll take some pics of the current way that it's in my truck later on.

It turned out that I wasn't as happy with rear firing as I thought I would be. It didn't sound right. So now it's firing forward and ports to the driver side. I'll take pics of that and my amp mounted soon.

Not bad at all. The sub is asking for more power, and it'll see Woody's 2500d that he's buying from tommyk pretty soon. There's still more kick left in it.

actually external ports are for small enclosures that require too long of a port to fit in the enclosure.
how far is the external end of the port from the side wall?

And to make you a bit louder:)
There is somewhere around a 6 in gap, plenty of room.
