Maintenance of Rigging
Suspension systems can degrade with time,
exposure to atmospheric conditions and ware,
they require regular inspection and routine
maintenance to insure the speaker cluster
and fittings are secure. The installation must
be inspected for fatigue at least annually. The
inspection must include a survey of all load
bearing surfaces including those attached
to the building for signs of deterioration or
any other condition that may decrease the
strength of the installation or loudspeaker
enclosure.
Quest Engineering or its distributors are not
responsible for the non legal application or
misuse and abuse of its products by installers
and product users.
HPI212S Rigging Points
The HPI-212S casing contains 10 internal
threaded inserts for flying the box. Rated M8
eye bolts can be attached to the casing for
flying the box in a permanent installation.
The HPI212S as Part of a Larger
System
The HPI series is designed to be multi-
functional. Both the HPI212S and HPI18LP
can be used as a stand alone sub bass or
independently crossed over, as band pass
elements in a multi-way system.
WARNING
Do not attach the HPI212S to the HPI110 box inserts if flying the sub
bass as part of a flown array.
When used in conjunction with a HPI-212S,
the HPI212S can be band-passed with an
electronic x-over to reproduce a very low
frequency range to provide the very low sub
bass of electronic music and the HPI-212S
can be set at a frequency range to provide the
“punch”. The ideal frequency range to set the
individual box element is as follows:
HPI212S band-passed 75-120 Hz.
HPI18LP band-passed 30-75 Hz.
The filter type needs to be a 24 dB per octave
slope.
Depending on the method of installation and
room acoustics, minor variations to these
settings may be necessary for ideal results.
The HPI Ground Stack Footprint
The physical footprint allows the HPI212S to
interlock with the HPI18LP in a ground stack.
Up to three HPI110 or HPI210 box elements
can be stacked in a ground stack array.
CAUTION
It is strongly advised to attach the
array flying plate to the top of the
ground stacked boxes to prevent any
box elements being dislodged from
the ground stack . A ratchet strap can
also be used to secure the boxes .
