PROFESSIONAL SOUND SYSTEM
Low Frequency Enclosure
Model SB-3 W
APPEARANCE Stands for the position of the gravity
center when two speaker units(HLS30S2-
) are installed inside.
Note:Be sure to install each speaker unit from
the inside of the enclosure baffle board.

2. Enclosure
3. Nut for horn mounting bracket(HY-M94)
4. Hole for suspension kit(HY-3 S)
5. Rear board
6. Terminal panel
7. Input terminal
FEATURES
1. Low frequency, vented(bass-reflex) enclosure for permanent installation.
2. Creates a woofer system that reproduces low frequencies with high efficiencies when two
HLS30S2- woofers are mounted. The tuning frequency is 75Hz.
3. Each speaker unit is mounted to the baffle board from the rear of the enclosure, facilitating
maintenance after installation.
4. Creates a wide-range, high-efficient standard speaker system(GS-302W) when used in
conjunction with a LE-M94 CD horn, a HFD-220- compression driver, and two HLS30S2-
woofers.
5. It is possible to suspend the SB-30W with the optional HY-3 S suspension kit.
6. It is easy to mount the LE-M94 to the enclosure with the optional HY-M94 horn mounting
bracket when the standard speaker system is configured.
7. Large input screw terminal.
. A protective punched-metal grille.
9. Finished with paint(dark gray).

Installation Examples
The SB-30W is a fixed enclosure for reproducing low frequencies. A high-efficient low
frequency speaker system consists of the SB-30W and two HLS30S2- woofers, and a high-
linearity, wide-range two-way speaker system is configured in addition to TOA's LE-series
constant directivity horns and HFD-series compression driver.
When driving the speaker system with multi-amplifier operation, the time alignment and
speaker system phase can be set to their optimum performance conditions by using our
integrated sound processor "SAORI" as a divider. When driving the standard speaker
system(GS-302W) with passive operation, use the optional HNW- 00 dividing network and two
HLS30S2-16 woofers.
Mounting the Low-Frequency Loudspeakers
1. Remove the rear board.
2. Screw each speaker unit to the baffle board from the inside of the baffle at places. (The
screws are attached to the speaker unit.)
3. Connect the cables to the speaker unit. Connect the red cable to the red terminal and
connect the black cable to the black terminal.
4. Replace the rear board by screwing at 16 places.
Note:Be sure to install each speaker unit from the inside of the enclosure baffle board.
Suspending the Enclosure
Before mounting the speaker unit, mount the HY-3 S suspension kit to the enclosure. For
details, refer to the HY-3 S's instruction manual.
When suspending this speaker, make sure to suspend it after investigating structure of
installation locations, and confirming that the suspending wires or belts are heavy-duty to this
speaker.
Mounting the Horn
When the standard speaker system(GS-302W) is configured, the constant directivity horn LE-
M94 is mounted on the SB-30W with the horn mounting bracket HY-M94. For details, refer to
the HY-M94's instruction manual.
Mounting the Dividing Network
When using the HNW- 00 dividing network, detach the terminal panel at the back of enclosure
and mount the HNW- 00 dividing network. For details, refer to the HNW- 00's instruction
manual.
Installing the Enclosure
If necessary, attach the provided rubber spacer to the four locations at the bottom of the
enclosure.

Note
The HNW- 00 dividing network and two HLS30S2-16 woofers
are required when driving the speaker system with passive
operation.
SAORI Setting
1. When driving the speaker system with multi-amplifier
operation using SAORI, set the channel divider module for a
long delay type(IS-110DL4 and IS-110DL2) as shown in the
following diagram.(F1 as low-frequency and F2 as high-
frequency)
2. Since the level setting value is set to standard values which
are used the same type amplifier's output power for each
band, it may have to be adjusted according to the location
and condition of the area in which it is used.

Suspending the GS-3 2W
When suspending the GS-302W, make sure to suspend the
constant directivity horn to upper direction using the optional
HY-3 S suspension kit as shown in the figure.
Never suspend it to lower or horizontal direction.
For mounting the HY-3 S to the enclosure, refer to its
instruction manual.
Caution
When suspending this speaker, make sure to suspend it after
investigating structure of Installation locations, and confirming
that the suspending wires or belts are heavy-duty to this
speaker.
TOA takes no responsibility for any accidents or injuries caused
by faulty mounting methods or poorly selected mounting
locations.
