Hi
All Vifa tweeters have a positive indicatuion of +/- its "moulded" into the face plate on the back can be hard to see but it is there - another way to chack is apply a battery to the terminals of the tweeter, positive to the positive terminal and negative to the negative terminal will result in a outwards movement of the dome.
Thanks
Peter
