American Bass Elite 1244 box volume

Anyone know the box volume for American Bass elite 1244? On here it says 1.2 cu.ft. On American Bass website it says 2.5 cu.ft. What should I go by? 2.5 just seems a bit big don’t you think?

Definitely go with the 2.5 from the website. It's always better to more air volume 2to3 cubic feet for a subwoofer like a 10",12" or a 15" is generally good.

What we actually hear is the air moving, so more air volume is more Db + more spl & power. 1.5 would sound weak+ not as much low end.
