I don't get it! Why is there a condensor/capacitor (the green thing attached to the tweeter wires) when there is a "frequency switch-BMW language" (the sausage like grey foam wrapped filter) as well? I thought that all filters were a combinatiion of both coil (going to the low frequency speaker) and a capacitor (leading to the high frequency tweeter). Are there two sets of capacitors in this set then? What does that mysterious grey sausage contain?

Since there are two different connections to the Tweeter (Business radio SA662 to B2) and Professional radio SA663 to B4) the inline condensor/capacitor (green thing) must be reduntant in one of the connections B2 or B4, I guess. The question is which one?
