pop filtering

[steven]

i tired this simple experiment agers ago, with a photo flash unit from a pocket camera. first id charge up that 330 volts capacitor in the photo flash unit of the camera, then id dump that charge right smack into the coil of a small speaker, but i was exspecting the speaker to blow but it dident it just made this loud poping noise, and if i put something small on the card board part of the speaker or speaker cone what ever you call it and this loud poping will send this object flying but as i exsperimented i decided to try it through vairious capacitors of different values , non electrolytics, so the higher the value the less louder the poping was so this was handy testing out the ability of these different capacitors in filtering that voltage i dumped into the speaker coil from the photo flash capacitor ,
