As much as I respect Vid's history lesson of "oh you think this is bad, you should see what we dealt with back in the 80's and 90's", I don't think this excuses Stern in current times. I mean if we all had that attitude about cars "oh hell, 1 out of 10 cars that rolled off the assembly line had issues that had to be reworked", we'd all still be driving lemons instead of pretty reliable vehicles from almost every manufacturer. It should be a race to the top, not the bottom.
Aren't Stern backboxes currently half metal half MDF? Maybe they should experiment with that concept for the bottom cabinet too? Maybe only the sides should be wood and there should be some sort of metal brackets in each corner that joins all 5 pieces together for a solid structure that requires no glueing, really no vendor to make cabinets (just paste whatever art needs to be on each flat piece of wood, and bolt it into the metal corner brackets on the production floor).
