TOA SPEAKER COMPONENT

LOW-FREQUENCY ENCLOSURE

SB-30S

DESCRIPTION

The TOA SB-30S is a vented, bass-reflex, low-frequency
enclosure for permanent speaker-system installations.

It serves as a low-frequency enclosure for the HLS30S2-8
woofer. It may be used in multi-amp systems employing
the TOA SAORI for optimal time alignment, phase
programs, equalization and channel divider functions.
The optional HNW-800 dividing network should be used
when operating the speaker system passively. The
optional HY-38S suspension kit may be mounted in the
SB-30S before the woofer is installed, and the LE-M94
may be attached with the HY-M94 horn mounting bracket.
A large screw terminal input panel ensures safe and solid
connections. The enclosure comes with a protective
punched-metal grille and a leatherette finish.

FEATURES

1. Low-frequency, vented (bass-reflex) enclosure for fixed
installations.

2. HLS30S2-8 woofer may be installed to produce a woofer
system that is highly efficient in reproducing the low­frequency response. Box tuning frequency (fb) is 75Hz.

3. Creates a wide-response, highly efficient speaker system
when used in conjunction with the LE Series horn, an HFD
Series compression driver and the HLS30S2-8 woofer.

4. SB-30S 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.

INSTALLATION EXAMPLES

The SB-30S is an enclosure for reproducing low
frequencies. A high-efficiency low-frequency speaker
system can be created by adding an HLS30S2-8 woofer.
A high-level, wide-range 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.

Installing the Low-Frequency Loudspeaker

1. Detach the protective punched-metal grille.

2.

Connect the cables to the speaker.

3.

Mount the 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 4 locations.

Suspending the Enclosure

Before installing the speaker, 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.

ARCHITECTS AND ENGINEERS
SPECIFICATIONS

The low-frequency enclosure shall be a TOA SB-30S 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 the HLS30S2-8 woofer unit. Box tuning
frequency (fb) shall be 75Hz. When installation with a suspended
SB-30S is required, the optional HY-38S suspension kit shall be mounted
to the SB30S before the woofer is 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 586(H) x 426(W) x 286(D)mm (23.1(H) x 16.8(W) x 11.3(D) in.).
Weight shall be 15kg (33 lb.), for the enclosure. The enclosure shall be
of particle board and shall come with a protective punched-metal grille
and a leatherette finish.

Mounting the Horn

When the speaker system is assembled, the LE-M94 constant directivity
horn is attached to the SB-30S with the HY-M94 horn mounting bracket.
For details, refer to the HY-M94s instruction manual.

Installing the Dividing Network

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.
