The density of the cabinet walls is key to minimizing vibrations of the speaker cabinet.
Denser cabinet walls won't do much; they need to be stiffer. With only a 3:1 difference in stiffness between MDF and hardwood you're going to do a lot better there through bracing.
Bracing is the key to minimizing vibrations.
Beam stiffness is proportional to the cube of thickness. A single 1 3/4" deep x 3/4" wide hardwood brace is stiffer than a 3/4" thick panel that's a foot wide.
You're better off gluing a single 1x4 piece of Douglas fir on than making a panel out of hardwood.
Stiffness is also inversely proportional to the cube of the span.
