Real $1 Speaker Posted by: electroman49 Video duration: 424 seconds This was my first attempt at building a working speaker from scratch. The first voice coil was only 1.2 ohms and it loaded down the MP3 player. A second coil was wound that measured 5.6 ohms, and now the sound could be heard, only very quietly. The "ShoeBox 1000" high powered homebuilt amplifier didn't like the impedance of the speaker, and it let me know in a BIG way!
