Jbl N7000 Schematic [best] -

The N7000 is a passive second-order LC (Inductor-Capacitor) filter. While specific internal component values can vary by production era, its general schematic includes:

Avoid shady “paid schematic” websites. The N7000 design is public domain. No one should charge you for this 70-year-old circuit. jbl n7000 schematic

The N7000 is nearly 70 years old. Electrolytic capacitors dry out. Inductors drift. Resistors burn up. When these crossovers fail, they don’t just sound bad—they can destroy your tweeters. A failed capacitor can send low-frequency energy to a delicate 075 tweeter, frying its aluminum voice coil in seconds. The N7000 is a passive second-order LC (Inductor-Capacitor)

is a classic passive dividing network designed to add a ultra-high-frequency (UHF) driver, typically the No one should charge you for this 70-year-old circuit

If you have an original N7000 but the schematic is smudged or missing, you can trace it yourself. Here is the physical layout JBL used:
