i want to say the test proved it definitively but to be honest unless i really crank it (seemed like we shouldn't do that from
post), i can't be positive just based on putting my hand on the cone...
any other way to test? will an impulse measurement with no delays set help?
Have you tried a close mic measurement, like within a few a few inches of the cone and look at the IR? That way you are seeing what is actually the end result in case a wire or another setting is causing the polarity flip.
