Hi, I am absolutely with you. Just using mass to cure everything is plain stupid and a game of luck. I didn't use the 90mm parts for rigidity. I did some "acoustic room tuning" to the inside of the enclosure that works much better with my speakers than furious attacks of wadding. With stacking of wood sheets in some areas a wall thickness got to 90mm.
If I want the ultimate stiff, non-resonant enclosure I'd use an engineering trick and tension the cabinet walls. Say use 32mm ply, drill some holes through parallel walls, stick a threaded rod through and tighten the rods. Tight.
For a shelf speaker I'd use 2 10mm rods through the sidewalls and one 10mm rod through top/bottom.
