SPECIAl CONSIDERATIONS FOR BUIlT-IN INSTAllATIONS
Fathom subwoofers are designed to be "built-in" friendly. All typically
needed controls are located on the front panel above the woofer. A Fathom can
be easily integrated into custom cabinetry by following a few simple guidelines.
1) Allow 4 inches (10 cm) of clear space behind the Fathom's amp panel for
adequate cooling and connector clearance.
2) On all other sides (except the bottom), allow at least 2 inches
(5 cm) clearance for adequate ventilation.
3) While the Fathom generally runs only warm during spirited operation, we do
recommend that adequate heat vents are included in any custom cabinet which
encloses the Fathom. A pair of 3 inch (7.5 cm) diameter vents near the bottom of
the cabinet and near the top of the cabinet, will allow cool air to circulate over the
amp panel of your Fathom subwoofer system keeping it cool and happy.
4) Your Fathom subwoofer is capable of moving substantial quantities of
air. If the front of the Fathom is covered by a custom grille, the grille
must have AT LEAST 108 square inches (700 sq.cm.) of vent area for
the f113, AT LEAST 85 square inches (550 sq.cm.) for the f112, and
AT LEAST 60 square inches (386 sq.cm.) for the f110. These areas
are equal to the woofer cone area for each model and will ensure
that the Fathom's output is not choked by the custom cabinet.
