Thanx Wayne, I know that trick. That's how I was able to tell that the Jensen P8RL midranges were wired out of phase. (both of these drivers are in the original Heathkit SS-1 cabinets). When I looked @ horns, one was wired one way, + and -, the other one, the other way. I found some photo's of them wired inside cabinets, on the internet, but it's hard to tell because back then a lot of speakers were wired like auto speakers are. There really isn't any established color code convention. I thought someone on this forum might have had some experience with them. I can't see down the horn enough to see which way the diaphram moves to establish polarity. Because of their age, I'm really hesitant to open the diaphrams. They do look like they'd be replaceable, but I'd rather not.
