Anyone ever hear of a scrape test for the 123a-1 driver? If so, how is it done?:confused:

OK
I'll bite
A scrape test???? As in Voice Coil rub?? Just run a sign sweep and don't try moving the cones by hand to check. Very tight in that gap.

OK, and then what? do I listen for something or look for something?
:confused: :beamup: Can you give more information?
OK
Let's start over. Why are you asking about this?? A sine sweep will tell you if you have a missaligned voice coil. You will hear a rather distinctive buzzzzz usually at a particular frequency range but sometimes all the time when you do the sweep.

OK Rob, I got you now! I understand fully. I am asking because, although I am quite familiar with electronics, I do not know it all when it comes to speakers! If I did, I wouldn't need guys like you ! THANKS ROB.:yes: :cheers:
Your welcome
