CAUTION!
For the eight models, S112IV, S112IVS, S115IV, S115IVS,
SM10IV, SM12IV, SM12IVS, and SM15IV, use the TS-30,
TS-40, TS-80, or TS-90 speaker stand by Ultimate Support
System, Inc. sold separately.
When using speaker stands, observe the following precau-
tions to prevent the speaker stands from falling over or the
speaker system being dropped.
• Use the speaker stands with their legs fully opened.
• Do not place more than one speaker on the same speaker
stand.
• Tighten fastening screws securely.
• Remove the speakers from the stands before moving the
stands or adjusting their height.
• Implement measures to prevent the speaker stands from
falling over.
• Use the TS-30, TS-40 at no higher than 130 cm for the
S112IV, S112IVS, SM10IV, SM12IV or SM12IVS and at
no higher than 120 cm for the S115IV, SM15IV and
S115IVS.
• Use the TS-80 and TS-90 at no higher than 140 cm for
all speaker models.
• The top tube of the TS-30 and TS-40 speaker stands has
a diameter of 1-1/2", but is tapered to 1-3/8" at the top to
fit in the mounting holes on the eight models named. If
you should remove the top tube from a stand, be sure to
insert it with the narrow end up when reassembling.
The SW118IV, SW118IVS subwoofer has a metal socket
to allow mounting of a satellite speaker. Do not use a pole
longer than 56". Use a pole with an outer diameter of 1-3/
8".
SPEAKER HANDLES
The handles on your speakers are for transportation. They
are not designed for suspension or hanging. Only the "A"
versions of these speakers are designed for suspension.
Please consult a qualified engineer for proper hanging
techniques.
Fly-Ware
Model S115IVA, S115IVAS, S115IVA-OAK
These speakers are supplied with Fly-Ware rigging hard-
ware installed. The following notes explain how to prepare
these speakers for suspension.
IMPORTANT! This material does not explain how to
suspend speakers.
To properly suspend any speaker, a knowledge of struc-
tural engineering and structural rigging is REQUIRED.
Suspending loudspeakers requires special tools and tech-
niques. Do not attempt to suspend any speaker system un-
less you have received specific training to do so.
The improper installation of flying speakers can result in
bodily injury or death.
Always consult a licensed engineer to verify the design of
any suspended system. In addition, please follow these
safety steps:
• Use only hardware specifically designed for rigging ap-
plications.
• Always use an independent safety suspension system as
a backup.
• Get professional help.
To prepare these speakers for suspension:
1. Remove the flathead screws from the top of the speaker.
Note: The 3/8" flathead screws use a 7/32" hex wrench.
Take care not to remove both screws from each corner,
as the internal bracket will fall inside the loudspeaker.
2. Apply a drop of thread locking adhesive to the end of
the threads of the eyebolts.
Note: Please use the supplied eyebolts found in the car-
rying handle of the speaker. If you use any part other
than that supplied, be sure it is Load Rated and know
that it will be de-rated if not suspended so that the pull
direction is in-line.
3. Install the eyebolts into the holes on top of the speaker
and finger-tighten.
4. Securely tighten the eyebolts. Hand tighten +1/2 turn.
5. Inspect the other six (6) flathead screws, making sure
they are tightened down.
