Reduce air volume - Built box and is a little to big

[XPerties 10+ year member]

My measurements were great on paper but after assembling it, glue/screw and resin I'm at 1.42 with sub Displacement - 0.17 cu. ft. which brings me to 1.25 and the optimal for a 12 RE sex is 1.0. I know using poly fill increases the size but is there anything I can add to decrease size?

I thought of back wall stacking 2x4 but the box is now resin and sealed. Local audio store suggest foam...Your thoughts?

depending on how much you want it down you could do deadener because that added 1/8 of an inch all around.

I need to bring it down .25 which would be a perfect 1.0

Put a couple pieces of 2x4 in there. I don't think you'll notice a difference between 1.0 cubes and 1.1 cubes. This isn't rocket science.

Wow....Considering this is my first box build I guess I should have asked my stupid question at a different forums board. I do appreciate the answers I received from the more mature members and to others who feel the need to belittle those who are not as "smart" as yourself, karma's a true fact in life.
