Generally, it is not recommended. The N7000 was designed for specific vintage JBL drivers. Loudspeaker technology, driver materials, and impedance characteristics have changed significantly. Using the N7000 with modern drivers could result in poor sound quality, an uneven frequency response, or even damage to your speakers.

The N7000 utilizes a 12 dB per octave slope to protect delicate tweeters while ensuring a smooth transition in the high-frequency range. Using the N7000 with modern drivers could result
The low-pass portion of the schematic ensures that frequencies above 7 kHz are rolled off, preventing the woofer or midrange driver from attempting to reproduce high frequencies outside its linear operating range. 2nd-Order LC Filter.
In an era of digital signal processing and 24dB/octave active crossovers, the humble JBL N7000 schematic looks primitive. But there is magic in that simplicity. The gentle 12dB slope, the lack of a midrange high-pass filter, and the series-inductor tweeter circuit create a unique phase relationship that many vintage JBL fans swear is un-reproducible with modern gear.
