Actually 3 questions. 1) I'm assuming the crossover coils (inductors) don't have any polarity right? They're just coils of wire and it should not matter which direction the current flows? 2) Is the glue just to hold the component on the circuit board or does it provide any other function like insulation, dampening, etc. 3) If a couple inches of the coil came unwound I assume that wouldn't be a big deal?
The scenario would be if a coil fell off of the board and became un-soldered could you just solder it back on without worrying about polarity and then just secure it to the board with a plastic tiewrap.
