As noted in the Owner's manual, if you have confirmed the wires are connected correctly at the speaker end and the AVR end, then simply IGNORE the warning and move on. It's very rare that the mfr has reversed the wires by mistake, rather more likely due to the placement of the speaker in the room.I have hooked up JBL E100 as fronts to my Denon 6700. During the Audyssey calibration I got a warning that the polarity on my left speaker is reversed. The funny thing is, having swapped the wires and re-running calibration, I still got the same message!
Did anyone else encounter the same issue? What could be a reason for this?
