How to make your own speakers
Find copper wire, packing tape, and a strong magnet.
While there is a lot of calibrating that goes into high end speakers, the basic technology is actually pretty simple. An electrical current is run through a wire that is attached to a magnet.
This current makes the magnet vibrate, and those vibrations are picked up by our ears as sound. To hear the sound well you should also get a small plastic tupperware or cup.
