Printed circuits
Universal circuits or grid grids are ideal for creating crossovers.
The universal circuits each have 3 adjacent holes in a row, which are connected by the copper coating. This structure has proven successful in the construction of small series crossovers.
If you do not want copper rails, we recommend wooden panels or grating made of epoxy fiberglass laminate, where you place the components on one side and connect the wires on the back.
