Ensure the new capacitors have a voltage rating of at least 100V to 250V to handle high-power audio transients. Cleaning the L-Pad
The N7000 schematic represents a relatively simple yet highly effective, passive crossover design. Components in the Circuit
At first glance, the N7000 schematic appears as a complex web of lines, resistors, capacitors, and inductors. However, closer inspection reveals a deliberate architecture centered on the crossover network—the heart of any multi-driver loudspeaker. The schematic tells the story of signal division. It illustrates how the incoming audio current is meticulously split, sending low frequencies to the woofers and high frequencies to the tweeters.
| Specification | Value | Source | | :--- | :--- | :--- | | Crossover Frequency | 7,000 Hz | | | Filter Slope | 12 dB/octave | | | Input Impedance | 4 to 16 Ohms (compatible) | | | High-Frequency Control | Continuously variable (L-Pad) | | | Product Weight | 0.9 kg (approx.) | | | Key Components | 1.5 uF capacitor, 0.6 mH inductor | | | Release Date | 1957 | |
Modern Applications: DIY Enclosures and Legacy Audio Systems
The JBL N7000 is a legendary loudspeaker system known for its exceptional sound quality and durable design. While I couldn't find a readily available schematic for the N7000, I can offer some interesting facts and a "good story" about this iconic speaker.
The N7000 includes a 3-position switch to adjust the attenuation levels, allowing the listener to set the output to 0, -3dB, or -6dB to match the main system’s impedance, typically 16 ohms. 2. Key Component Values Filter Point: 7000 Hz. Impedance: Designed for 16-ohm systems.
If you have landed on this page, you likely fall into one of two categories. You are either a vintage audio enthusiast holding a dusty, non-functioning JBL N7000 crossover network, or you are a DIY speaker builder looking to clone one of the most legendary frequency dividers in hi-fi history.
The dividing network is a cornerstone of vintage audio engineering, designed specifically to integrate ultra-high-frequency transducers (tweeters) into high-fidelity loudspeaker systems. Known for its role in systems utilizing the JBL 075 "Bullet" tweeter, the N7000 is a 7,000 Hz crossover that acts as a vital link, protecting the tweeter while adding brilliance to the overall sound.
