I wan‘t to make these, but idk how, and i cant afford them. how do i do this?
Jeff is correct in how to make the speaker, but you'll still need an amplifier to drive it.
It is basically an electromagnet attached to a cone inside a magnet. So you will need a steel bar, thin copper wire, a round magnet with a hole in it. The electrical sound wave travels along the copper wire used for the electromagnet. It creates a magnetic field and is repelled by the round magnet. The electromagnet moves away from the round magnet and since it is attached to the cone the woofer moves. good luck with this sounds fun.
