Hi folks, decided to sign up after lurking for a while. I recently got an Ampeg SVR-212. The previous owner had taken it apart to see what was inside but wasn't completely sure whether he had reconnected the woofers with their correct polarity. It's a small job to open it up and my gut feeling tells me to wire the front woofer and the tweeter with normal polarity and the rear facing one with reversed polarity. Anyone that can shed some light on this?
