I am getting a d9 this week and i have a 1 cu ft sealed fiberglass box for my sub. I plan on either getting my box modified with mdf rings to give me more depth or just inverting it for now until I get more $. I know that inverting a sub makes the box bigger. The recommended box space is between .6-1.2 but I'd like to keep it around .9

How do I go about making the box smaller, anything specific I put in? What is a good amount to put in (of said object) to lower it by .2 ft?

Thanks!

you can use mdf wood to take up the space, you can glue together about 5 pieces of .75" x 10" x 10" board then screw them to the back of the box. that should bring the volume down .22 cu ft.

Use anything that'as dense and won't cause any weird resonance....... MDF is the best rout.

Lowe's or Home Depot sell it by the 4'x8' sheet. $19.99 a sheet, the last time I looked.

A local lumberyard would also sell it.
