Speaker Cables
Speaker cable needs to be as heavy gauge
as conveniently possible for low-loss results.
Light gauge cable (below 1.5mm) will create
extra resistance and waste amplifier power.
This particularly applies to long speaker
runs. The amplifier’s damping factor statistic
(“punch” for the non technical) is greatly
diminished, so keep your speaker cables
short and as heavy gauge as practical.

Overhead Installation and Rigging
“Rigging” is used in this manual as a general
term referring to fixed mounting or hanging
suspension as well as the hardware used for
such mounting and suspension. It also applies
to temporary and permanent installation.
Mounting or rigging overhead suspension of
any speaker box load can result in serious
injury and equipment damage if not done
correctly. Rigging and installation personnel
must determine the mounting or suspension
method that takes into consideration all loads
that the speakers and rigging system will be
subjected to. All such work must be done
in accordance with and in compliance with
all government, state, and local regulations
governing such work.
NOTE: The user assumes all responsibility
and liability for the proper design, installation
and use of any rigging and mounting systems
for Quest Engineering loudspeakers.
NOTE: Accessory items are available from
Quest engineering and aftermarket suppliers
to facilitate suspension, wall, ceiling, or other
rigging. When using these items, review all
enclosed documentation and carefully follow
all instructions and safety precautions.

Rigging and Safety
Whether mobile sound or fixed installation, for
best and safest results your speakers need
to be installed and positioned correctly. Just
placing a mid-high on a sub bass and pointing
it at the crowd will not be a good show if it
vibrates off and falls onto a member of the
audience. The same goes for hanging a box
from a lighting bar with non rated hardware
and relying on luck for it to stay there.
So if you are going to use the Quest speakers
for anything other than a fold-back monitor….
Read the rigging part of this manual and
follow the instructions .
There are many
books on the subject of overhead rigging
and it is recommended that any installer
is educated on this subject to a level of
thorough knowledge especially in the area of
load limits and weight ratings.
