THE SUBWOOFER
Derived from JL Audio's revolutionary TW5 design platform, the subwoofer
used in the Fathom IWS employs our patented thin-line woofer technology
to achieve extreme excursion capability and ultra-low frequency extension.
To reduce the possibility of damage during home construction or during the
enclosure's installation process, the subwoofer is not pre-installed. The subwoofer
should only be installed after all aspects of construction and wall finishing have
been completed.
THE GRILLE ASSEMBLY
The Fathom IWS enclosure uses a grille that mounts directly to the wall studs
instead of the enclosure. The grille assembly consists of a removable outer metal
mesh and grille tray unit. The grille's design allows the enclosure to attach to the
wall without making actual hard contact with the enclosure itself.
This unique mounting method allows the enclosure to essentially "float"
within the wall cavity without transferring vibrations to the wall itself. A plastic
paint guard is included to protect the woofer from overspray during painting. The
outer metal mesh and grille frame should be painted separately to prevent them
from sticking together.
The grille assembly is available in three size range options to accommodate
nine different wallboard thicknesses. It is critical to use the correct grille size
for proper fit. Refer to the chart below to verify that your grille assembly is
compatible with the wallboard thickness used in your application. Do not
attempt to use or modify a grille that does not fit your application.

1/2" to less than 13/16"
