Crossover PCB for the Tarkus DIY Speaker Design

Description

Custom printed circuit board designed for the crossover of the Tarkus DIY speaker design by Paul Carmody.
Take the guesswork out of crossover assembly, these boards make the assembly process quick and straightforward.
This board measures 6.75" x 6.75" and features large solder pads and copper traces for great electrical connectivity.
I had a small run of these PCBs made up on commission and I'm listing the left over's from that batch.
Includes:
1x Crossover PCB for the Tarkus DIY speaker design.
4x 2-pin terminal blocks which accept up to 12 gauge wire.
4x Snap in PCB standoffs.
4x Mounting screws (screw finish may vary).
Requires:
Crossover components for the Tarkus speaker design.

Assembly:
Glue components to the correct positions on the board (hot melt glue works great). Secure inductors with non metallic cable ties. Solder components leads to the pads on the bottom of the board. Attach wires from input and drivers and mount crossover board.
