While this is functionally correct, the fact is that some manufacturers do not correctly identify their speakers. JBL actually is inverse polarity , meaning that if you apply a positive voltage to the RED terminal the speaker moves IN, which is not the way it should be moving. Thus if you put JBL's in a cabinet with other brands, there may be polarity issues, which will result in PHASE problems.Originally posted by: ScottMac
Even if the wire is unstriped with paint, one side usually has a roughness or parallel lines moulded into it (look at a brown "lamp cord" sometime).
As mentioned, as long as you maintain polarity, it doesn't matter which side is desgnated plus or minus.
Good Luck, HNY!
