WARNING!!!DON'T DO THIS!!!!!(What was recommended by Joe A.) I'm sure he meant well, but isn't familiar with the Altecs. I have put low voltages through an Altec 802-8g, on the order of .5 volt and used a magnifier to observe displacement, and the terminal markings are correct - the red is indeed positive. Looking from the back of the driver this would be the left bottom push terminal. Hooked up accordingly, this would give the dome a positive displacement down the throat of the driver, out into the horn.
How one would determine polarity of Altec 808-8G ?
I have a pair of Altec 808-8G drivers. There is no polarity marking on the driver. Can anyone help me to determine the polarity of the drivers? Thanks
