Boxes are sized to suit the driver you pick, performance can be altered a little to suit what you are doing, but is mainly a function of the driver.
Mostly you can build a sub box any shape you want as long it has the internal volume required for the driver.
Picking the best driver you can afford will dictate the internal volume of the box with a little wiggle room to skew the performance up or down a little...….shape can be whatever works.
Sealed is the easiest to build with less complexity overall in the box and the DSP settings...….I think sealed provides a little extra safety when you really start pushing it watching movies with some extra volume.
Its best to decide what you want the driver to do first...…..then pick the driver that will do that and then build a enclosure for that driver.
For movies you want a large driver 18 inches or bigger, you need lots of excursion which is the Xmax figure in the driver specs to dig down low and move some air. Usually these take pretty big enclosures 6 to 15 cubic foot depending on the driver to go low.
I would not get too worried about sealed or ported on your first build, it takes a few different builds to tell the differences in sound signature and it takes some time living with each to get a good overall feel for which one you like the best......not something that's going to happen in a couple 45 minute sessions or in a showroom.
I would pick a driver in the 300-600 dollar range. With lots of excursion, build a sealed box for it, get a miniDSP as you will need that for any sub ……….build the right sized box for it in the shape you want to fit your room and usage, use REW to play with everything and have fun.
You can always build a different box later, that's the cheap part...……
I built sealed as my first pair of 18`s and its been over a year now and no regrets...…..I would like to try a ported box in my room with my drivers just to see the difference, but in no way want to build a ported box because the sealed is lacking, they dig down well below 10hz in the sealed boxes as room gain with a sealed box is crazy.
In the end sealed or ported is fine......but sealed is easier and more forgiving.
