Titanium diaphragms question

[JDub]

I just bought a set of midrange diaphragms from Simply Speakers. The terminals on them have 2 different sizes, one about .256" and the other about .210". The original diaphragms have terminals that are both the same size (2 x .210") and they have a paint mark next to one terminal; there are no marks on the new diaphragms. So I assume the different size terminals identify + and -, but my question is - which is which????

Thanks in advance.

Generally speaking (if you google it) the small terminal is negative
