Set of four high-quality printed circuit boards that allow owners of the legendary JBL 4300 Series 4-way Studio Monitors, or those who are building their own DIY clones, to upgrade their existing passive crossovers to modern standards using polypropylene film capacitors, air-core inductors, and the charge-coupling (biased capacitor) technique used by JBL in their ultra-high-end studio monitors such as the DD67000.
The Full Board Set comes with 2 main boards and 2 auxiliary boards, supporting both full passive (single-amp) and bi-amp configurations. Detailed PDF documentation is provided with purchase of the boards, which contains full parts lists for each of the supported systems, as well as instructions on how to assemble the boards and integrate them into your system.
NOTE THAT COMPONENTS ARE NOT INCLUDED. THIS LISTING IS FOR PRINTED CIRCUIT BOARDS ONLY. Use the parts list to procure components for your speaker configuration.
