Im trying to make a box that i build alittle smaller on the inside .. i know that i can add
MDF to the sides but that would me my last resort.. i want something easier then that is there anything like that???

people told me if its a sealed box i can use polly-fil/fiberfill or fiberglass insulation.

would that work?




heres the box

sounds like he wants to make his box smaller by adding polyfill...

adding polyfill will make your box seem larger,not smaller.you need to add solid objects to make it smaller. pices of mdf,2x4's anything solid

if you use polyfill, your subs will feel that your box is BIGGER.

That's why I said it made no sense about what he wanted to do. He wants to make it smaller by making it larger....

i personally feel like you would be better off making another box. BTW that box is huge

High Density Foam Blocks, not the spongy kind. Can make your own with expanding foam a cardboard boxes. Just fill and tape shut. Foam will fill and compress into solid blocks. Can then be cut to downsize box to correct IT CF.

i think his box is huge just because he intergrated an AMP rack on top

calculate your inner volume.... then decide where you want the desired volume to be.... subract that value from the total you have now... what the difference is, would be what you would need to add as a solid object... it would be easy to use scraps of MDF in places that could also double as a brace... Once you do that. you are all good.
