DRAIN PLUG IS REMOVED
This option is recommended:
• In applications with dry soil where occasional water may accidently enter the
enclosure. Use of gravel and sand will allow any water that gets into the sub enclosure to
properly escape.
e.g. Las Vegas, Inland Southern California, Southwest desert
For bollard with drain plug removed:
1. Dig a hole for the subwoofer, about 18'' in diameter and 18'' deep.
2. Lay gravel rock (3/8'' size recommended) for a depth of min. 3'' below the bottom of
subwoofer enclosure.
3. Place the subwoofer as level as possible and not tilted.
4. Take care to not block the drain hole by direct contact with gravel rock.
5. Use 2'' depth of loose dirt to cover the top of subwoofer enclosure.
5B. BURIAL DEPTH
NOTE:
DO NOT BURY THE ENCLOSURE UNTIL ALL WIRING HAS BEEN COMPLETED.
The subwoofer enclosure should be buried to a level where the dirt covers the wire nut and
protruding wire at the top of enclosure. Do not bury excessively deep. Care should be taken
to ensure that all bollards extend to the same height above ground.
