SUSPENSION KIT
Instruction Manual
HY-38S
General Description
The HY-38S speaker suspension kit is designed for use with TOA SB-38S, SB-30W and SB-30S low frequency, vented
(bass-reflex) enclosures.
Handling Precautions
Consult a construction expert to ensure mounting bolts
and cables are made of sufficiently strong material to
securely hold the weight of the speakers.
Ensure all mounting eyebolts are securely tightened and
can not be loosened by prolonged exposure to speaker
vibration.
For maximum security, the use of a 6-point suspension
method such as shown in Figure 1 is highly recommended.
TOA takes no responsibility for accidents or injuries caused by
faulty mounting methods or poorly selected mounting locations.

SB-38S/SB-30W/SB-30S Speaker Installation
The speaker enclosures have been pre-fit with sus-
pension bracket mounting holes. Working from inside
the enclosure, use a screwdriver to push out the hole
plugs from the four locations where the brackets will
be installed. Referring to Figure 2, install the brackets
and eyebolts, ensuring all screws are securely tight-
ened.
Note: Horizontal mounting method for the SB-38S SB-30S
As shown in Figure 3, an anchor nut for eyebolt
mounting is already installed inside one corner of
the enclosure, therefore only suspension bracket
No.1 and the eyebolt need be installed at this
location. Refer again to Figure 2 to install the
brackets for the other three points, ensuring all
screws are securely tightened.
