SPECIAL CONSIDERATIONS FOR BUILT-IN INSTALLATIONS
The Dominion™ subwoofer can be integrated into custom cabinetry by
following a few simple guidelines.
1) Allow 4 inches (10 cm) of clear space behind the amp panel of your Dominion™
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 Dominion™ generally runs only warm during spirited operation, we
do recommend that adequate heat vents are included in any custom cabinet that
encloses the Dominion™. 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 Dominion™ subwoofer system, keeping it cool and happy.
4) Your Dominion™ subwoofer is capable of moving substantial quantities of air. If
the front of the Dominion™ is covered by a custom grille, the grille size must be
AT LEAST equal to the woofer cone area for each model to ensure the output is
not choked by the custom cabinet. Refer to the chart below for recommended
vent areas for each model.
