is a classic frequency dividing network (crossover) primarily used to integrate high-frequency "ring radiator" tweeters like the variant; decreasing this value shifts the crossover point
The is a legendary passive crossover network, often referred to in technical documentation as the 3105 , designed specifically to integrate ultra-high-frequency drivers—namely the JBL 075 (Bullet Tweeter) or 077—into high-quality two-way or three-way loudspeaker systems. Known for its role in the "Olympus" and other iconic systems of the 1960s and 70s, understanding the JBL N7000 schematic is essential for vintage audio enthusiasts looking to restore, maintain, or replicate the classic JBL sound.
The core design of the N7000 is a 2-way frequency dividing network. It features a crossover point at 7,000 Hz, which is exceptionally high compared to modern standards. This high transition point was intentional; it allowed the woofer to handle the majority of the vocal range while the 075 tweeter added "brilliance" and "shimmer" to the top end. The network is an 8-ohm design, ensuring compatibility with the standard impedance of JBL professional series drivers.
Original units were built with high-quality, hand-wound aluminum foil capacitors (not electrolytics) and low-loss inductors held to . REBUILD your JBL crossovers. LX5, N7000, N2400 ... - eBay Known for its role in the "Olympus" and
Typically used for high-frequency drivers like the JBL 375, 075, or 077.
Often found in parallel in JBL's high-frequency filtering designs to achieve specific values and improved performance.
