The boring stuff.
[edit] Using the same terminal cups as my last sealed 3-way. So I can use the same passthrough plate that I made for doing measurements and crossover prototyping. It is a piece of 1/2" plywood with screw holes in the same location as the terminal cups. A hole is drilled in it for 3x pairs of wires to pass through, sealed with silicone. A simple gasket was made of 1/16" hobby foam sheet.
If I were to do a sealed 2-way I’d probably just use a quad binding post cup.
I wish I snapped up some of the JFcomp. terminal plates. Since they are all the same size you can swap 1x,2x,and 3x pair terminal plates around. Very useful for measuring with a pair of terminals per driver, then swap for a single-pair plate when finished.
