Cup speaker is louder than this real one?!

Learn how to make a speaker!!! You just need copper wire, a cup or bowl, and a strong neodymium magnet. We then and compare it to a professional $169.99 speaker. Along the way we will see how the changing the cup to a bowl, using different sizes of magnets, and different numbers of wire coil, and using an amp affect the output and loudness of our speaker. We then compare our very best speaker with the store bought UE mini boom to see which is louder!
