Sealed box for TS-W2000SPL

[Jonahdude 10+ year member]

I'm about to buy a Premier TS-W2000SPL subwoofer, and I'm not sure how to build the box. http://www.pioneerelectronics.com recommends 1.5 cu ft, but is that before or after displacement? It has two voice coils... do I need two terminal cups? How would changing the box size affect the sound? Should I use polyfill? I need to caulk the inside, right? How should the sides overlap? Blah blah blah? Blah, blah blah?

I'M SO CONFUSED! HELP ME!

dont lose notihn by sealing the inside.

box should be after displacement. 1.5cu feet is pretty big for sealed than usual

only need one terminal cup

box size: the larger, the less power it needs, n viceversa. it would affect sound too.
