5. INSTALLATION
The Subwoofer System can be installed on the floor or can be suspended from a ceiling, etc. When suspending, use the
optional HY-PF7B or HY-PF7W Speaker Rigging Frame.
4. INPUT CONNECTORS
For installation method, refer to the instruction manual supplied the HY-PF7B or HY-PF7W.
• Use the suspension wires, chains, and anchor shackles that are
strong enough to withstand the total weight of the speaker and
mounting hardware.
Failure to do so may cause the speaker to fall, resulting in personal
injury.
• Owing to the unit's size and weight, be sure that at least two
persons are available to install the unit. Failure to do so could result
in personal injury.
