Wilson Audio has conducted many hours of research on the impact of mate-
rials on speaker enclosure performance. Through this effort, Wilson pioneered the
use of non-resonant materials, first with the use of mineral filled acrylic in the
WATT, and continuing with the further development of proprietary materials for
X-1 Grand SLAMM and MAXX. Even the best materials are not suited to all
aspects of enclosure construction. Therefore, like all Wilson loudspeakers, the
Sophia is constructed of several exotic materials chosen for their specific perform-
ance attributes relevant to different portions of the enclosure.
Sophia is constructed using non-resonant, high-density, composites which
are then highly-cross braced to further reduce cabinet resonance. Each of these
composites meets and exceeds the highest of ANSI test standards for its use, while
offering very tight tolerances, high hardness, uniform density, and dimensional sta-
bility. In the most critical areas of the enclosure, the Sophia uses our proprietary
"X" material, a very dense, strong composite developed for the X-1 Grand SLAMM.
The high hardness of these composites offers excellent acoustical properties.

Wilson Audio has conducted exhaustive research into the best adhesives to
permanently bond our speaker enclosures. This is often an overlooked element
crucial to the proper performance of a loudspeaker. Correct modulus of elasticity,
coefficient of thermal expansion, and natural frequency response are just a few of
