SAFETY REGULATIONS
Please read this manual carefully and in its entire-
ty. It contains important information regarding safety
issues, including guidelines for general safe use of
rigging systems as well as advisories on govern-
ment regulations and liability laws. The suspension
of large, heavy objects in public places is subject
to numerous laws and regulations at the national/
federal, state/provincial, and local levels. The user
must assume the responsibility for making sure that
the use of any rigging system and its components in
any particular circumstance or venue conform to all
applicable laws and regulations in force at the time.
GENERAL SAFETY RULES
• Carefully read this manual in all its parts
• Respecttheworkingloadlimitsandmaximumcon-
gurations of the elements and of any third-party
component (such as suspension points, motors,
rigging accessories, etc...)
• Do not incorporate any accessory not provided
by Outline; all damaged or defective components
must be replaced only by equivalent parts ap-
proved by Outline
• Ensure personnel health and safety, ensure that
no one is standing under the system during the
installation, ensure that all personnel involved in
the installation are equipped with personal safety
devices
• Always double check that the elements are cor-
rectly connected before suspending the system.
The rigging elements are easy to use, however the
installation shall be carried out only by qualied per-
sonnel that are familiar with the rigging techniques,
safety recommendations and with the instructions
described in this manual.
All mechanical components are subject to wear and
tear over prolonged use as well as corrosive agents,
impacts or inappropriate use. For this reasons us-
ers have the responsibility to adopt and adhere to a
schedule of inspections and maintenance. Key com-
ponents (screws, connecting pins, welded points,
rigging bars) must be inspected before every use.
Outline strongly recommends to carefully inspect
the system components at least once a year, report-
ing in a written document the date, the name of the
inspector, the points checked and any anomalies
discovered.

STSUB-215 DESCRIPTION
SAFETY PRECAUTIONS
The STSUB-215 loudspeaker mounts two bass-re-
ex loaded 15’’ neodymium woofers.
The enclosures are constructed with birch ply n-
ished with ‘outSIDE’, an extraordinarily tough and
waterproof elastoplastic coating which interacts
with the cabinet material to provide extreme levels
of long-term protection. The outSIDE coating is just
one of the fundamental parts of the outSIDE concept,
which is a set of conceptual and implementative op-
erations leading the product to be suitable for expo-
sure to aggressive weather conditions.
STSUB-215 are intended to be used in installations
and must be installed following the local and regional
safety rules. Specic rules must be applied to the rig-
ging structures that have to hold the assembly of one
or more devices and to the cables for the connection
to the amplier. Periodic controls must be performed
at regular time intervals according to local laws, to
the presence of additional safety devices (such as tab
washers against screw loosening) and to the work-
ing conditions of the components (exposure to heavy
weather, heavy use, etc..).
An example of tests includes: a transducer test (i.e.
to be performed before and after every use), a visual
test for the rigging safety (i.e. to be performed every
six months), a visual test for the paint and wooden
external parts (i.e. to be performed once a year).
Additional tests must be performed after every un-
usual event such as incorrect use, very heavy storms,
etc...
The results of the periodic tests must be reported
on a document like the one at the end of this manual.

RIGGING INSTRUCTIONS
RIGGING POINTS POSITION
RIGGING STRUCTURE
Each STSUB-215 speaker requires an external rig-
ging structure to support each single element and
the total weight of the cluster if more than one loud-
speaker is used. The rigging hardware must be de-
signed according to the local laws and local safety
factors and considering the total load of the system,
the dynamic factors inducted by vibrations, winds and
mounting procedures. The rigging system shall allow
also safe mounting and dismounting operations and
easy visual control.
Each STSUB-215 offers sixteen M10 threaded fe-
male points. Four rigging points are available on
each edge between the bottom, the side and the up-
per panel of each STSUB-215 cabinet. Two of them
are close to the front panel (as shown in the picture
below) and two are close to the rear panel. Please
refer to the overall dimensions drawings for the exact
position of each point.
Figure 1: Detail of the position of two rigging points on a STSUB-215
The external rigging hardware must provide
support for each loudspeaker. This means that the
loudspeakers are NOT intended to support other
loudspeakers or other weights.
When multiple loudspeakers are used to build
a so-called “line array”, the external rigging must
embrace each loudspeaker and the entire array, as
shown in the picture below.

RIGGING POINTS DETAILS
The rigging points consist of unperforated inserts
designed to hold a M10 bolt while protecting the
speaker from water. The inserts are made of galva-
nized steel to prevent corrosion and are oiled to offer
further protection. Even with these features it is sug-
gested to protect against water the points that are
not used.
The length of the screw must allow the effective
use of 22 mm of thread and must not exceed the max-
imum depth of the insert (27 mm), as shown in the
picture below. It is strictly forbidden to use a shorter
screw for safety reasons and to avoid damages to the
loudspeaker.
Figure 2: Rigging points details: each rigging point is made of a special insert that can receive a
M10 bolt and ensure no water penetration inside the loudspeaker.
Figure 3: Correct use (on the left) and incorrect use (on the right) of the rigging points. The bolt
must be long enough to fully engage the internal thread considering also the external hardware
and accessories.

The external hardware must be designed to be
placed as close as possible to the loudspeaker. It
is strictly forbidden to use rigging hardware that is
at any distance from the loudspeaker at the rigging
points. Tightening the screw with hardware that is
not in contact with the enclosure may result in dam-
age to the rigging points or to the cabinet if excessive
torque is applied.
The connection of the external hardware to the
rigging points must be made using proper bolts (the
usual class is 8.8), following the above prescriptions
and applying a controlled torque value with the help
of a torque wrench (dynamometric key).
The tightening torque denes the axial force be-
tween the bolt and the insert and depends on the
frictions with the washer and the thread of the insert.
As a result of this, in order to apply the same axial
force, smaller torque is required if the parts are lu-
bricated.
The torque to apply has been dened considering
the resistance of the insert, of the wood and the in-
teraction between the parts. The maximum tighten-
ing torque is 15 Nm for lubricated parts.
Tightening the bolts with higher or not controlled
torque might result in damages and risk for the
safety.

The handles, which make part of the side panels
of the cabinet, have been made for handling STS-
UB-215 easily during the connection to the external
hardware. Warning! The handles must not be used
neither for rigging, nor for the connection to safety
locking systems.
The STSUB-215 loudspeakers have been designed
to resist to outdoor environment in all weather con-
ditions. This is the result of a technology called “out-
SIDE” which is a set of conceptual and implementa-
tive operations leading the product to be suitable for
exposure to aggressive weather conditions. The out-
SIDE coating technology is a special procedure which
implements two layers of polyurea paint plus one
layer of UV- resistant nish with calibrated elasticity.
This kind of nish avoids polymerization and yellow-
ing of the polyurea, whereas the calibrated elasticity
helps keeping in time the perfect adherence between
the layers in order to adapt to the dimensional varia-
tions of wood caused by “wet-dry” cycles of outdoor
environment. It is to consider that the total thickness
of the layers is of 2 mm (to add to the overall dimen-
sions given in the technical drawings).
The external rigging hardware must be approved
by a licensed professional engineer
USE OF THE HANDLES
RESISTANCE TO WATER
AMPLIFICATION
STSUB-215 uses two 15” woofers and a single am-
plier channel is required. The wiring to these com-
ponents is available on a 4-connector barrier strip on
the side of the loudspeaker.
The woofers are connected as shown in the picture
below, in standard operations the links between pins
1 and 4 and between pins 2 and 3 allow the use with a
single amplier channel. It is also possible to remove
the links and use all four connectors, i.e. to use a
double wire connection (useful for long cables to re-
duce the cables’ resistance) or to drive independently
each woofer.
A proper size amplier and DSP are required to op-
erate the loudspeaker ensuring safe working condi-
tion and expansive dynamics.

CABLE SELECTION AND AMPLIFIER CONNECTION
The connection from the amplier to the loud-
speakers must ensure proper energy transmission
and small losses. A general rule is that the cable’s
resistance should not be greater than the 10% of the
minimum impedance of the components to be con-
nected. Each Stadia 100 LA, when used in bi-wiring
has a nominal impedance of 4 Ω (LF) and 8 Ω (HF) and
a minimum impedance of 3.2 Ω (LF) and 8.1 Ω (HF).
The resistance of the cable can be found in the cat-
alogues of the cable manufacturers. These usually
report the resistance of the length of one conductor,
so this value shall be multiplied by 2 to consider the
total round trip distance.
The resistance of the cable (round trip) can also be
estimated with the following formula: R = 2 x 0.0172
x l / A. Where ‘R’ is the resistance in ohm, ‘l’ is the
length of the cable in meters and ‘A’ is the section
area of the wire in square millimeters.
The following table reports the resistance in ohm
per kilometer for different wire sections (calculated
with the formula above) and the recommended max-
imum length of the cable.

WEATHERPROOF CABLE PROTECTION
The weatherproof cable protection consists of a
moulded protection cap (1), a neoprene gasket (2) and
a set of screws (3) (see gure below), with the cable
gland already mounted on the cap.

Gasket (bonded to the cap) (2)
Moulded protection cap (1)
The neoprene gasket serves for the protection of the
cable connections from water and dust ingress, so it
is necessary to check the gasket conditions and in-
tegrity before mounting the protection cap.
Please respect the sequence when mounting the
washers: rst the large series at washer (for the
protection of the cap from scratching), and to follow
the split-lock washer in order to prevent the unwant-
ed unscrewing.
