Plywood.

Plywood is a type of engineered wood made from thin sheets of wood veneer, called plies or veneers. The layers are glued together, each with its grain at right angles to adjacent layers for greater strength.There are usually an odd number of plies, as the symmetry makes the board less prone to warping, and the grain on the outside surfaces runs in the same direction. The plies are bonded under heat and pressure with strong adhesives, usually phenol formaldehyde resin,making plywood a type of composite material. Plywood is sometimes called the original engineered wood.

A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength. It has replaced many dimensional lumbers on construction applications for these reasons. So Why not a loudspeaker cabin?

The plywood layers in a loudspeaker cabin gave extremely good results with almost zero vibrations.Except the plywood layered construction that we use we also have different layers of wood veneer in each plywood piece. The result is a solid and firm loudspeaker cabin.Also the loudspeaker cabin is much lighter with a plywood construction instead any other typical material.
