) in the signal line to the tweeter, protecting it from high-current low frequencies.

In the N7000 design, the schematic likely reveals a high-order crossover topology. This is not merely a simple filter; it is a defensive wall protecting delicate high-frequency drivers from the destructive energy of bass notes. By tracing the path of the inductors (coils of wire), one can see the engineering meant to maintain a stable impedance curve. This is crucial. A schematic that shows careful impedance matching indicates a speaker that will be "easy to drive" for an amplifier, ensuring that the amplifier doesn't clip or distort at high volumes. The N7000 schematic, in its layout, prioritizes this synergy between amplifier and transducer. jbl n7000 schematic
