General Info about Setting Up with Speaker Stands
Heads-up: Always make sure the speaker stand is on solid footing and
be sure to observe the manufacturer's instructions as to its maximum
load-bearing capacity.
Caution!
• Use only speaker stands that are stable enough to prevent accidental
tipping. Ensure the speaker stand is designed to handle the cabinet's
weight. Adjustable stands' highest setting must be limited to prevent the
combination of speaker stand and speaker from tipping. This applies when
setting the stand on a fl at, horizontal surface.
• When setting up on an uneven or sloping surface, make sure the speaker
stand's base is secured to prevent accidental tipping, either by attaching
suitable weights to the base or taking other measures to secure the
stand.
• The use of any other fi xtures or fi ttings can result in instability that may
result in injury.
Rigging:
All XA and FA models can be fl own by installing the AP-8 attachment and
steel cables or chains to their rigging points, or by installing the proper truss
brackets.
FA models provide heavy-duty 4x5 mm threaded inserts in the side-
mounted shell grips serving to attach the HK Audio TB-45N or TB-45NQ
(the Q stands for quick-release pins). XA models' wedge monitor-like angled
panel does not accommodate a shell grip, so they come with reinforced 2x8
mm threaded mounting points that let you bolt on the HK Audio TB-28N
truss bracket. Mounting instructions are enclosed with the truss brackets.

LINEAR 7 FA enclosures feature angled side panels for easy clustering.
4.2 L7 118 Sub A
Deploy the L7 118 Sub A as you would any other direct radiating subwoofer.
However, do not stack the bass bins when confi guring cardioid setups.
Instead, place them side by side, maintaining a distance of at least one
meter from walls.

When is it a good idea to go with a cardioid setup?
While speakers are able to throw midrange and high frequencies in
directional patterns, low frequencies tend to radiate in all directions.
Excessive bass levels can often be a problem on and behind the stage. And
promoters are increasingly making demands to limit sound systems' low-
end reach, for example, in festival tents at urban venues. Such demands
for limiting low-range frequencies' range are best met with cardioid setups.
With its hardware appointments and fi lter sets, the L7 118 Sub A provides a
fast, easy way to confi gure eff ective cardioid setups.
