This is not a picture of my specific unit (can't get my camera working) so I found these.
I'm checking to make sure these are wired correctly and in general they are.
Meaning, my +/- comes from my amp and +/- goes to the first driver and the second driver is being fed -/+ so that one is pushing when one is pulling.
Here's my question....
I did the 9 volt battery test.
When I touch + to + on the driver on the right (magnet hidden) the driver pulls in. When I touch + to + on the driver on the left (magnet on top), the driver pushes out.
This is in general find & dandy.... but.... since this is a horn, does it matter what the initial phase of the drivers are?
Should the above happen or should the drivers work in the opposite direction.
Since these are not like direct radiator woofers, I don't know which direction which one should move when hit with a traditional +/- to +/- contact.
I do have the ability to invert the polarity in my active crossover but rather just get them wired right from the beginning.
These were built by someone else so I have no instructions on them.
According to your battery test it seems like your wiring is correct because I always thought a positive voltage should cause compression within the throat of the horn. (i.e. both cones should move towards the hidden magnet)
However your wiring seems reversed when compared to the drawing because, according to the instructions, both cones should move towards the visible magnet when a positive voltage is applied.
I wouldn't worry too much about getting the absolute polarity correct.
I wired up everything according to the instructions but still needed to invert the polarity going to the sub to match the phase up with the rest of my speakers.
However, unknown polarity reversals might also be occurring in one of the three electronic devices I have connected in series between my AVR and Sub Amp.
