In-ground Installation and Connection
of IG-Series Loudspeakers
Depending on the type of installation, direct burial of the speaker cables from the amplifier
to the loudspeakers may be adequate, or the use of a 1” to 1-1/2” ID conduit may be required
for protecting the wires from possible physical damage if future excavation or other alter-
ations are anticipated in the area of the install.
An IG-Series loudspeaker can accommodate
either method, including the entry and exit
conduits sliding conveniently under the bottom
of the enclosures through provided wiring/
conduit channels.
Direct Burial of Cable or Conduit
WARNING: Customer is responsible for the wiring materials to/from amplifier and
to/from other speakers/subwoofers, as well as the selection of the installation area.
It is recommended that a professional be consulted when connecting speakers if
the installer does not have sufficient knowledge in working with electrical components.
Connections can be protected using
one of the following methods:
• RECOMMENDED: Optional NEAR
Model IE1 Direct-Burial Junction
Box (IP67 Rated) allows convenient
access to connections
(Detail A)
• Solder connection wires together
using waterproof heat shrink tubing
to make a seal
• Make connections with immersion-
resistant Crimp Splices (Raychem)
• Using Grease Wire Caps, available
from several suppliers (such as Orbit,
Toro Irrigation, etc.)

In-ground Mounting/Burial
of IG-Series Loudspeakers
When excavating for burial of an IG-Series Loudspeaker select an area that will support
the depth needed to accept the enclosures. The IG Loudspeakers’ burial depth should be
up to the speaker’s “NEAR Badge”
(A)
. In addition to the depth the speaker requires as
above instructed, it is recommended that further excavation be made beneath each enclosure
so that 6 inches of crushed stone can be added to provide proper drainage. Some type
of standard drainage fabric should then be placed as a buffer between the speaker and the
crushed stone base.

In-ground Install Angles
of IG-Series Loudspeakers
The IG-Series Loudspeakers were designed with a slightly angled driver so that even
if the enclosure is situated on a level plane (see Install 1 & 2) any accumulated moisture
can be channeled out of the speaker through the two Drainage Canals (A) located on
either side of the speaker. Even if choosing a more sloped install angle (Install 3), the
speaker will still drain water from the driver when Drainage Canal is angled downward (B).
