Why shouldn’t one use MDF in pro speaker cabs?

Uptown Funk is why. If it ever gets wet (as these did) and Uptown funk is played, you get sawdust.

These are Baltic birch cabs coated with duratex. Except for the handle cups apparently. I’ll have to have a word with the guy that built them. Notice the way it shredded. The Duratex had to be holding it together for some time.

99% of the time, things that aren't already being done aren't being done because they don't work. The other 1% is split evenly between fools and geniuses.

MDF has it's place, and that's in the home. It takes veneer better than plywood, so if you're going to veneer, the cab is never going to be moved, and it's safe from getting wet use MDF. The only reason to use MDF in pro-sound cabs is because it's cheap. If they skimp on the cab material they skimp on the drivers and everything else, engineering included.

Yep. And if you’re having someone build for you... check on the work to make sure shortcuts weren’t taken. I picked these up painted and with damping installed. I had no reason to believe shortcuts like this would be taken, but they were.
