If you can see or feel the diaphragm, you can possibly tell what direction it is moving when a small voltage is applied. You can connect a 1.5v battery across the terminals and see what direction the diaphragm moves. This is simple on cone or dome tweeters, but not so easy on compression drivers and horns. In that case, you need acoustic measurement equipment.
