One passive crossover board per speaker, so build two. Single-sided, through-hole only, CNC isolation-milled with an 0.8 mm end mill (the DTU 62768 process).

The MCP3208-CI/P is an analog To Digital Converter made by Microchip Technology in a PDIP-16 package with 16 pins. -40℃~+85℃ 100kHz 12 1LSB 2.7V~5.5V 8 SPI PDIP-16 Analog to Digital Converters (ADC) ROHS.
PCBKit's library has its KiCad symbol (Analog_ADC:MCP3208, from KiCad's library) and its footprint (Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. 31 are in stock at JLCPCB (part C1543277). 3 open-source boards in 3 repositories on GitHub use it.
