Speaker Enclosure 4" filled with sand

I printed this out of PLA. I had chat gpt generate an openscad file based on the properties of a dayton 8ohm full range 4" speaker. I shelled it out and filled it with sand and mortar mix and sealed it with liquid nails. I added a veneer. Each speaker enclosure weighs roughly 5 pounds. Great mid ranges but will need to add tweeters and a mini subwoofer for my desk!
