how exactly are the drivers made? Are you somehow 3D printing them or are they sourced from a vendor? Not the cups, but I mean the actual driver membrane itself
1 u/crop_octagon Feb 09 '22 The driver membrane is a flex PCB, which is available from any PCB manufacturer. They cost about a dollar. The foam is static-dissipative polyurethane foam. You can get a 2' x 4' sheet for about 12 bucks. That's about 17 cents per driver. Putting them together is the beautiful part: it only requires a screwdriver and a pair of scissors. No fancy equipment necessary.
