Wilson’s inventory of synthetic materials used for the enclosure’s panels, modified and filled structural polymers and resins, has long moved on from Corian, the marble dust-loaded acrylic chosen for the original WATT. The panels mostly comprise synthetic structural material of differing densities, stiffness, and mechanical loss, or self-damping.

These “materials” include “S,” an epoxy-bonded composite optimal for the mid and treble driver baffles, and “X,” a filled, cured phenolic resin with high damping. The latest “V” formulation is a further development with still better vibration control. Accordingly, the “V” option has been chosen for the heavy-duty Puppy bass system’s top panel, which optimally mounts the machined alloy plate supporting the WATT assembly.

As a group, the Wilson-specified materials are consistently isotropic when required and although very hard, remain machineable, have essentially no grain or directional properties, and readily accept durable enamel lacquers for a very wide range of finishes. For the WATT/Puppy, in addition to five standard high-gloss colors which include GT Silver and Galaxy Grey, there are a further seven Upgrade finishes and 11 Pearl finishes in combination with seven grille colors. Finally, there is the modestly discounted “no grille option.”
