Installation Examples
The SB-38S is a fixed enclosure for reproducing low frequencies. A high-efficient low
frequency speaker system consists of the SB-38S and one HLS38UL-8 woofer, and a high-
linearity, wide-rage 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-382S) with passive operation, use
the optional HNW-800 dividing network.
Mounting the Low-Frequency Loudspeaker
1. Remove the rear board.
2. Screw the speaker unit to the baffle board from 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 12 places.
Note: Be sure to install the speaker unit from the inside of the enclosure baffle board.
Suspending the Enclosure
Before mounting the speaker unit, mount the HY-38S suspension kit to the enclosure. For
details, refer to the HY-38S'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-382S) is configured, the constant directivity horn LE-
M94 is mounted on the SB-38S 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-800 dividing network, detach the terminal panel at the back of enclosure
and mount the dividing network. For details, refer to the HNW-800's instruction manual.
Installing the Enclosure
If necessary, attach the provided rubber spacer to the four locations at the bottom of the
enclosure.
