2.5 cube feet suubwoofer ported box

I took the displacement form both woofers and ports, but I builded the box at 2.4 feet so its 0.35 off, would that drop db's are hurt the woofers, but the box sounds good.

it's off by .35 how? bigger? or smaller?

it want hurt the subs n anyway if its bigger it will drop alil bit lower mayb a db and the oppsite if smaller and if its just .35 off then u could make a ring 2 go under both subs and that will get alil back for you so u dont have to build another 1 but thats only if the box is to small if its to big just add some bracing on the inside to make up the extra air space
