TOA SPEAKER COMPONENT
LOW-FREQUENCY ENCLOSURE
SB-30W
DESCRIPTION
FEATURES
The TOA SB-30W is a vented, bass-reflex, low-frequency
enclosure for permanent speaker-system installations.
It serves as a low-frequency enclosure for two HLS30S2-8
woofers. It may be used in multi-amp systems employing
1. Low-frequency, vented (bass-reflex) enclosure for fixed
installations.
2. Two HLS30S2 woofers may be installed to produce a
woofer system that is highly efficient in reproducing the
low-frequency response. Box tuning frequency (fb) is 75Hz.
3. Creates a wide-range, highly efficient speaker system
when used in conjunction with the LE Series horn, an HFD
Series compression driver and two HLS30S2-8 woofers.
4. SB-30W may be suspended by using the optional HY-38S
suspension kit.
5. Speaker system configuration allows for easy mounting of
LE-M94 to the enclosure with the optional HY-M94 horn
mounting bracket.
6. Large, screw terminal, barrier-strip input panel.
7. Optional HNW-800 cross-over network with HF
equalization can be mounted in the supplied input panel
opening.
8. Protective punched-metal grille.
9. Leatherette finish.

APPEARANCE AND DIMENSIONAL DIAGRAM
The SB-30W is an enclosure for reproducing low frequencies. A high-efficiency low-frequency speaker system
can be created by adding two HLS30S2-8 woofers. A
high-level, wide-response two-way speaker system can
be configured by adding TOA’s LE Series constant directivity horns and HFD Series compression drivers. When
driving the speaker system with multi-amplifier operation,
the time alignment, phase program, equalization and
channel divider functions can be set to their optimum performance conditions by using the TOA SAORI integrated
sound processor. When driving the speaker system in
passive operation, use the optional HNW-800 dividing
network and two HLS30S2-16 woofers.
Installing the Low-Frequency Loudspeakers
194 (7.64)
1. Detach the protective punched-metal grille.
2. Connect the cables to the speakers.
3. Mount each speaker unit in the enclosure and tighten the screws at
the 8 locations. Use the screws provided with the speaker.
4. Mount the protective punched-metal grille to the enclosure and
tighten the screws at the 9 locations.

Suspending the Enclosure
Before installing the speakers, mount the HY-38S suspension kit in the
enclosure. For details, refer to the HY-38S's instruction manual.
When suspending this speaker system, be sure to investigate the
structure of the installation location, and confirm that it is adequate for
the weight of the components in the system.
Mounting the Horn
When the speaker system is assembled, the LE-M94 constant directivity
horn is attached to the SB-30W with the HY-M94 horn mounting bracket.
For details, refer to the HY-M94’s instruction manual.

SPECIFICATIONS
The low-frequency enclosure shall be a TOA SB-30W or approved
equivalent. The enclosure shall be a vented, bass-reflex low-frequency
unit intended for permanent speaker system installations. It shall serve
as a low-frequency enclosure for two HLS30S2-8 woofer units, Box
tuning frequency (fb) shall be 75Hz. When installation with a suspended
SB-30W is required, the optional HY-38S suspension kit shall be
mounted to the SB-30W before the woofers are installed. The LE-M94
may be attached with the HY-M94 horn mounting bracket. A large
barrier-strip input panel shall ensure safe and solid connections.
Dimensions shall be 880(H) x 440(W) x 300(D)mm (34.7(H) x 17.3(W) x
11.8(D) in.). Weight shall be 22kg (49 lb.), for the enclosure. The enclosure shall be of particle board and shall come with a protective
punched-metal grille and a leatherette finish.
When using the HNW-800 dividing network, remove the input panel at
the back of the enclosure and mount the HNW-800 dividing network in its
opening. For details, refer to the HNW-800’s instruction manual.
Free-Standing Enclosure
If necessary, attach the provided rubber feet to the four locations at the
bottom of the enclosure for free-standing installation.
