The is a legendary frequency dividing crossover network engineered by James B. Lansing Sound, Inc. during the golden era of high-fidelity audio. Originally designed in the early 1960s, this passive, 2-way network is highly celebrated for adding ultra-high-frequency "brilliance" to classic horn-loaded systems. By crossing over at a remarkably high 7,000 Hz (7 kHz) , it seamlessly integrates the iconic JBL 075 ring radiator tweeter (or 077/2405) with mid-frequency compression drivers like the JBL 375. This configuration can be found in flagship speakers such as the monumental JBL Paragon and the JBL S8R system .
Before diving into the circuit topology, it is important to understand the operational parameters of the JBL N7000: 7,000 Hz (7 kHz)
The N7000 was primarily designed to accompany JBL's high-efficiency components, frequently paired with legendary drivers like the JBL 075 bullet tweeter or the LE85 compression driver. 7,000 Hz (7 kHz)
Allows you to adjust the volume of the tweeter to match the midrange/woofer. The 7kHz Crossover Point
Both versions effectively serve the same function—high-pass filtration at 7 kHz. 4. Restoring and Rebuilding the N7000
The input from the amplifier/preceding crossover connects in parallel with the 075 tweeter input. The capacitor sits in series with the positive line to the tweeter, creating a 6 dB/octave slope, while the coil provides a parallel path to ground, sharpening the transition to a effective 12 dB/octave for protecting the tweeter. 3. N7000 vs. N7000 16-Ohm: Are They Different?
