What should I use to take up excess enclosure volume?

My sub only requires .75 cube (sealed)



I have yet to actually figure out the volume of my fiberglass enclosure, but I'm pretty sure it's probably closer to a full cube or more.

Wondering if the shape of the blocks I use to take up space and positioning will matter at all?



I've seen everything from baby building blocks, triangle wedges, wooden spheres and even tennis balls used to fill the void on other builds, but not sure if any of this makes a difference in a sealed enclosure

Get a better sub with a big azz.

I’d leave it at 1 cube. Models better imo than .75 and still handles rated power.
