Well I am soon to make my own speaker in my electronics class. My Electronics teacher really likes me so he said I could use some speakers he has. They range from size probably from about the size of 1" through 4". They are only cheaper paper cones, probably like $5-10 a piece but I am just looking to make my first speaker and it won't cost me anything. Could someone recommend what types of things I will need to use in this project and what would be a good way to go about it.
