Since I've sworn off all social media, I'm back to mailing lists—hoping I'm still welcome here.

I'm currently rebuilding a crossover, where maintaining correct polarity is critical, especially since I sometimes run two Leslies. My research into the nomenclature for the *L* and *S* on S(ocket)7 and P(lug)7 indicates they stand for *Large* and *Small*, which makes sense, right? Further investigation suggests that the *Large* terminal is typically the positive connection.

Upon examining the cable that goes from the amp to the dividing network, the red wire is indeed soldered to the *Large* pin. Yet on the schematic, *L* is labeled **BLK** and *S* is labeled **RED**. Looking further down the signal path, it turns out *L (BLK)* is actually the positive, while *S (RED)* is the negative.

Any insights on this discrepancy?
