Polarity Pulse
A correctly wired cone pushes OUT on each click. Reverse = swapped speaker wires.
Phase / Polarity (Listening)

Stand between speakers. Flip R channel — in-phase sounds centered and solid, out-of-phase sounds hollow and diffuse.

200 Hz
Pink noise reveals polarity errors better — broadband cancellation is obvious. If flipping R sounds better, R speaker is wired backwards.
Channel Identifier

Left = 440 Hz. Right = 880 Hz. Alternating swaps every 1.5 s. Only the correct speaker should be playing.
