Re: Ported Enclosure Help
The port doesn't actually have to be inside the enclosure. What if you were to cut a hole in the false floor and mount the suitcase to it to where the sub is firing down into the wheel well, and you could also build a slot port that is actually contained under the cover?

Re: Ported Enclosure Help
Naiku,
I would do 2 sealed - better transients !
Al is right on the money, nice Al !
With cabin gain/transfer function - you won't miss 3 dBs.
Does your sub pass the test for down-firing ?
I WOULD THINK 2 SEALED !!!
16.85" l x 2" diameter could look like a shop vac hose lying on the floor next to suitcase if placed externally to suitcase enclosure. An actual piece of hose would work as port tube.
Re: Ported Enclosure Help
I prefer ported over sealed. I think I'd try to use a slot port before using 2 - 2" ports though because I'd have concerns about port noise.

That's not a bad idea at all, have to look into slot ports but that may make life easier.
Sort of wondering if I cut the entire bottom of the suitcase off, then use what is left as a cover and attach it to the wooden enclosure. Definitely looking at making a whole new floor rather than cutting the factory piece, especially as used tan ones are hard to come by.

Just don't forget to not subtract the vent volume fromt he enclosure. the last two of mine had external vents...
Re: Ported Enclosure Help
Or...put a plexiglass top on it, so when you open the suitcase, you can show off your cool enclosure guts.

Yeah, ports and the sub take up airspace, so make sure you include that in your box volume. If you go with an external port, you gain that airspace inside the box.
Re: Ported Enclosure Help
Ian, since the frequencies played by a subwoofer are omni-directional [ going everywhere or permeating the whole space inside your vehicle ], I forsee no problems for you with this endeavor.

This, and wrap the inside of the enclosure in that plaid fabric, to mimic the inside of a suitcase. Maybe even an airline tag glued in there too :D
