I’m curious about the sound when I swapped speaker cable, between positive and negative, at speaker terminal. At first, I believed the sound would be the same whatever wired conventionally or reversed polarity. After trial, however, I can hear the different of sound! Could anyone please confirm me that the wiring polarity, at terminal, is matter? Also, I used to see some speaker’s schematics, not sure if they were vintage AR speakers, were put the passive network components on negative line. It would be very helpful if anyone has a microphone setup for doing a frequency swap, please assist to measure the response and phase for both cases. Thanks in advance.
