TCS Arraying and Rigging
This document explains how TCS loudspeakers can be arrayed and the reasons for the rotatable
horns in some models. The TCS-122 and TCS-152 both feature Turbosound’s unique Dendritic high
frequency waveguide. This can be rotated for two reasons:
1. To allow a single speaker to be mounted horizontally but still retain the wider horizontal
pattern, or
2. To allow two or more speakers of the same to be arrayed with minimal interference
The second application is explained here in detail.
One of the benefits of the Dendritic waveguide is its exceptional coverage pattern and sharp edge-ofpattern cut-off as demonstrated in Flex Array. The sharp cut-off works either vertically or horizontally,
depending on which way the horn is rotated.
To explain this further, the TCS-122 and TCS-152
feature exceptional pattern control either left/right or
up/down depending on how the horn is rotated. This
allows them to be arrayed with adjacent speakers
without lobes or destructive interference. So the true
arrayable benefit of the Dendritic is
plane of the Dendritic device
up/down depending on orientation. The other plane
of the Dendritic device functions in a similar way to a
standard horn.
i.e. either left/right or
in the physical
The diagram here shows a TCS-122 with the horn in
two possible orientations. The one on the left is the
typical orientation, so for example the TCS-122/94
model has a dispersion pattern of 90 degrees wide
by 40 degrees in the vertical. The box on the right
shows the box with the horn rotated to give 40
degrees in the horizontal and 90 degrees in the vertical.
So the speaker on the left has a very controlled vertical pattern, whereas the one on the right (the
same speaker with the HF horn rotated) has a very controlled horizontal pattern.
The TCS-122 and TCS-152 are both available with three dispersion options: 60° x 40°, 90° x 60° and
60° x 40°. However note that only the 40 degree boxes benefit from being tightly arrayed, i.e with the
sides touching. So in a cluster of two or three tight packed boxes, you should use either the 60° x 40°
or 90° x 40° models and the horns should be orientated to give 40° dispersion in the horizontal plane.
The TCS-122 and TCS-152 are double trapezoidal boxes and it is this feature, in combination with the
rotatable horns that gives you the flexibility to build so many cluster options. The simple rule is that
the side that is touching the adjacent speaker needs to be orientated to 40 degrees.
The following options only apply to TCS-122 and TCS-152 models with Dendritic horns. The TCS-1561
and TCS-61 use conventional horns.

In this example the TCS-122/94
loudspeakers with horns in the
standard 90° x 40° orientation
are tight packed vertically
horn-to-horn, providing a
combined coverage of 90°
horizontal by approximately
80° vertical, with a useful
vertical beam and a mid-range
lobe that projects well down a
longer, thinner room.
These examples are based on the 90° x40° model. If using the 60° x40° models, a further three
coverage pattern options of 60° x 80°, 120° x 60°, and 60° x 80° would be available to you, depending
on the shape of the room.
The HF horns in this horizontal
array of TCS-122/94 boxes have
been rotated to give individually
40° horizontal by 90° vertical. The
horizontal coverage patterns add
up to give combined dispersion
of 120° horizontal by 90° vertical.
This example shows how the
same coverage pattern as the
vertical array on the far left can
result from a completely
different physical array. The HF
horns are rotated to give 40°h x
90°v and then the whole array
is assembled horizontally to
give combined coverage of 90°
horizontal by 80° vertical.
Rigging options
All of the TCS boxes have rigging points on the top, bottom and both sides, so they can be mounted
practically any way you like. For example, one option is to mount a single TCS-122 upside down to
get the HF waveguide closer to the audience.
Flying single boxes
This can be simply achieved with M10 eyebolts, WB-20 and WB-55 wall brackets, CB-55 ceiling
brackets, and OmniMount™ speaker brackets, for which bolt patterns are provided on the back of the

cabinets where appropriate.
Flying multiple cabinets
When creating loudspeaker arrays the essential components are a pair of steel flyplates fitted to the
sides of each flown cabinet, ensuring that all the rigging is steel-to-steel without any load being taken
through the cabinets’ woodwork. Sets of joiners mate with the flyplates to connect one cabinet to the
next adjacent cabinet.
Following is a summary of the kits required and their component parts.
FP-1 KIT 07G0335
Consists of a pair or steel flyplates that fit both the TCS-122 and TCS-152 cabinets.
1 x FP-1 kit is required for each cabinet that is to be arrayed.
The FP-1 kit includes two flyplates, four M10 x 40mm bolts and four M10 spring
washers.
FP-2 KIT 07G0340
Consists of a pair of steel flyplates for the flyable TCS-B15A and TCS-B15B
subs. 1 x FP-2 kit is required for each sub cabinet. The TCS-B15A is
dimensioned to fly with the TCS-122, while the TCS-B15B is dimensioned to fly
with the TCS-152.
The FP-2 kit includes two plates, four M10 x 40mm bolts and four M10 spring
washers.
With the flyplates installed on each box to be flown, now select the appropriate inter-cabinet couplers
to connect the flyplates from one box to the flyplates of another.
ICC-2H KIT 07G0345
A pair of steel inter-cabinet couplers for linking two TCS-122 cabinets together.
The couplers fit into the recesses provided in the flyplates and are secured using
the M10 bolts and washers that are supplied with the FP-1 flyplate kits.
ICC-3H KIT 07G0350
A pair of steel inter-cabinet couplers for linking two TCS-152 cabinets together.
The couplers fit into the recesses provided in the flyplates and are secured using
the M10 bolts and washers that are supplied with the FP-1 flyplate kits.
