We recommend the following system setup in stacking applications:
With three LINEAR 5
118 Sub HPA subwoofers placed one above the
MK II
other, the headstack consisting of two LINEAR 5
centrally on the top subwoofer (Fig. 6).
Heads up! Ensure additional tilt protection of the headstack, e.g. by using
an M20 threaded bolt (diameter 35 mm) with a minimum length of 50 mm.
Screw this onto the M20 thread of the subwoofer and place the speaker
fl ange of the lower LINEAR 5
MK II
There is also the industry-standard option of securing the headstack using
lashing straps.
Cluster
Placing two LINEAR 5
308 LTAs next to each other to form a cluster
MK II
extends the horizontal dispersion angle to approximately 140°. This requires
a cluster opening angle of 30° (approximately 24 cm, see Fig. 7). This is
important to minimise phase cancellation or elevations in the frequency
response (phasing eff ects) (Fig. 8). The use of a cluster is recommended
when a wide horizontal dispersion is required. The built-in MCT enables
acoustically correct clustering.

To implement this application in rigging operations, a set consisting of a
Pick Point and Cluster Plate is optionally available. This off ers three attach-
ment points for fastening slings and securing devices (e.g. steel ropes or
round slings). At the same time, it protects against unintentional horizontal
slippage of the speakers and off ers the advantage of a rigid connection
between the two cabinets.
We recommend the following system setup in stacking applications:
If three LINEAR 5
118 Sub HPAs are placed one above the other, the
MK II
cluster is placed centrally on the top subwoofer using the DFP double fl ange
plate or the PP-CP Pick-Point Cluster-Plate (Fig. 8). The Cluster Plate must
also be secured to the M20 fl ange of the subwoofer with an M20 screw or
the "HK Audio Tilt Unit", for example.
The same applies when using the "headstack cluster".
(Fig. 8)
For additional security, there is also the industry-standard option of secur-
ing the cluster using lashing straps.
Headstack Cluster
A headstack cluster is the largest expansion stage of the LINEAR 5
308 LTA. The combination of headstack and cluster is recommended when
a large sound coverage depth with simultaneous wide horizontal dispersion
is required. This results in a horizontal dispersion of 140° and a vertical
dispersion of +10°/-10° (Fig. 9). Using the PP-CP ensures that the correct
cluster angle for an acoustically correct cluster ring is fi xed. At the same
time, the PP-CP provides the rigging points to rig the cluster of 4 using a
steel cable or chain.
