The Bollard loudspeaker comes with a drain plug inserted at the bottom of its subwoofer
enclosure. If there is water ingress for any unavoidable reason, removing the drain plug will
allow for water to drain out. The drain plug is easily removable with a utility knife.
Drain Plug
A. OPTIONAL DRAIN PLUG
DRAIN PLUG REMAINS IN THE SUB ENCLOSURE
This option is recommended:
• In applications where ground water is at shallow depths and expected to rise easily
above ground level or areas with overall very wet soil.
e.g. Areas of Houston, Louisiana
For Bollard with drain plug inserted:
1. Dig a hole for the subwoofer, about 18'' in diameter and 18’’ deep.
2. Place the subwoofer as level as possible and not tilted.
3. Take care to ll empty spaces around drain hole where water might accumulate.
4. The subwoofer shouldn’t be in contact with large rocks or large empty holes below the
drain hole.
5. Use 2'' of loose dirt to cover the top of subwoofer enclosure.
