This is a speaker i made from scratch useing scraps i found around my home. The goal of this project was to make a speaker for free out of scrap. The other thing was that i did not use a pre made speaker to make this.
I will show how to make it, so you can build your own :)
Heres a video of the sound of my speaker.
