Unwrecking Your Tweeter

Don't you hate when you dent your tweeter. Of course, I removed the speaker grill, so I suppose I deserve what I get. But here I show how to repair a Tymphany, DA25BG08-06 dome tweeter by disassembling and undenting it from the inside out.

Great video ... Only want point out how you've used the word 'polarity' ... as incorrect. Since the magnet has fixed poles ... and the coil on the tweeter dome is also fixed... if all parts of that electromagnet relationship are fixed... polarity cannot be changed when disassembling or reassembling the parts as is. Only way I see it is possible... is attaching the leads incorrectly after the driver is reassembled. Great demo of how to fix the dome. Kudos on showing this method.

Yes well, that's true that the tweeter will "work", but the point is there is a labeling of the "positive" and "negative" on the leads of the tweeter. If you rotate the dome 180 degrees those labels will either be accurate or accurate, and certainly inconsistent with another specimen. That is intended to help you correctly and consistently connect the wires to all your drivers. Putting it together wrong makes that labeling wrong, so that someone has to use trial and error to get the right match of phase between their say left and right speakers in a stereo pair.

Also, the polarity does have an effect. One way makes the positive voltage push the dome outward and one way makes the positive voltage push the dome inward. By convention, the positive terminal on a driver is standardized to make it so that if you apply positive voltage to it, the the diaphragm will go outward.
