Low Frequency Enclosure
APPEARANCE
Model SB-38W
Stands for the position of the gravity
center when two speaker units(HLS38UL-
8) 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-940/HY-M94)
4. Hole for suspension kit(HY-700)
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
HLS38UL-8 woofers are mounted. The tuning frequency is 45 Hz.
3. Each speaker 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-3806W or GS-386W)
when used in conjunction with a LE-940 or LE-M94 CD horn, a HFD-260-8 compression
driver and two HLS38UL-8 woofers.
5. It is possible to suspend the SB-38W with the optional HY-700 suspension kit.
6. It is easy to mount the LE-940 or LE-M94 to the enclosure with the optional HY-940 or HYM94 horn mounting bracket when the standard speaker system is configured.
7. Large input screw terminal.
8. A protective punched-metal grille.
9. Finished with paint(dark gray).

Installation Examples
The SB-38W is a fixed enclosure for reproducing low frequencies. A high-efficient low
frequency speaker system consists of the SB-38W and t wo HLS38UL-8 woofers, and a high-
linearity, wide-range two-way speaker system is configured in addition to TOA's LE-series
constant directivity horn 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-3806W or GS-386W) with passive
operation, use the optional HNW-500 dividing network.
Mounting the Low-Frequency Loudspeaker
1. Remove the rear board.
2. Screw each speaker unit to the baffle board f rom the inside of the baffle at 8 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 20 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-700 suspension kit to the enclosure. For
details, refer to the HY-700's instruction manual.
When suspending this speaker, make sure to suspend it after investigating structure of
installation locations, and confirming that the suspending w ires or belts are heavy-duty to this
speaker.
Mounting the Horn
When the standard speaker system(GS-3806W or GS-386W) is configured, the constant
directivity horn LE-940 or LE-M94 is mounted to the SB-38W with the horn mounting bracket
HY-940 or HY-M94 respectively. For details, refer to their instruction manuals.
Mounting the Dividing Network
When using the HNW-500 div i d ing network, detach the terminal panel at the back of enclosure
and mount the di vi di ng network. For details, refer to the HNW-500's instruction manual.
Installing the Enclosure
If necessary, attach the provided rubber spacer to the four locations at the bottom of the
enclosure.

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 highfrequency)
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-3806W
When suspending the GS-3806W, make sure to suspend the
constant directivity horn to upper direction using the optional
HY-700 suspension kit as shown in the figure. Never suspend it
to lower or horizontal direction.
For mounting the HY-700 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
