Best way to decrease the internal volume of a sealed speaker?


I have a very fine sealed 0.75 cu foot cabinet that I would like to reduce the internal volume to about to about 0.45-0.65 cu feet. There is limited space to add things like bricks, pavers etc inside.
I am thinking of using some plastic containers with lids glued to the inside cabinet. Should they be filled with sand?

I’ll second georgehifi’s suggestion of liquid nail and bricks - with a twist; use 4 bricks. Glue them as close as possible to the centres of the sides and back and the available space near the tweeter on the front. Help strengthen and damp the walls while you reduce volume. I believe most cabinets will benefit substantially from bracing. Let you think about it. Cheers. Pete
