APPEARANCE
1. Panched-metal rille
2. Enclosure
3. Hole for suspension kit (HY-700)
4. Terminal board
5. Input terminal
FEATURES
1. Low frequency, vented (bass-reflex) enclosure for permanent installation.
2. Creates a woofer system that reproduces low frequencies with hi h efficiencies when the HLS46S-8
woofer is mounted. The tunin frequency is 40 Hz. It can also be used as a sub-woofer system for
ultra-low frequency output in lar e multi-way speaker system.
3. It is possible to suspend the SB-46S with the optional HY-700 suspension kit.
4. Lar e input screw terminal.
5. A protective punched-metal rille.
6. Leatherette finish.

Installation Examples
The SB-46S is a fixed enclosure for reproducin low frequencies. A hi h-efficient low frequency speaker
system consists of the SB-46S and one HLS46S-8 woofer. It also displays hi h-quality characteristics when
used as a sub-woofer system for ultra-low frequency output in lar e multi-way speaker system.
When drivin the speaker system with multi-amplifier operation, the time ali nment and speaker system
phase can be set to their optimum performance conditions by usin our inte rated sound processor
"SAORI" as a divider.
Mounting the Low-Frequency Loudspeaker
1. Detach the protective punched-metal rille.
2. Connect the cables to the speaker unit. Connect the red cable to the red terminal and connect the black
cable to the black terminal.
3. Mount the speaker unit to the enclosure and ti hten the screws to the ei ht locations. Use the screws
provided with the speaker unit.
4. Mount the protective punched-metal rille to the enclosure and ti hten the screws to the 14 locations.
Suspending the Enclosure
Before mountin the speaker unit, mount the HY-700 suspension kit to the enclosure. For details on
mountin , refer to the HY-700's insturction manual.
When suspendin this speaker, make sure to suspend it after investi atin structure of installation
locations, and confirmin that the suspendin wires or belts are heavy-duty to this speaker.
Installing the Enclosure
If necessary, attach the provided rubber spacer to the four locations at the bottom of the enclosure.

Use Example of Sub-woofer System
The followin illustration shows an example of use as a sub-
woofer system in a standard speaker system GS-3806W.

Appearance
SAORI Setting
1. When drivin the speaker system with multi-amplifier opera-
tion usin SAORI, set the channel divider module for a lon
delay type (IS-110DL4 and IS-110DL2) as shown in the fol-
lowin dia ram. (F1 as sub woofer system, F2 as low-
frequency and F3 as hi h-frequency)
2. The delay value of each frequency band is determined by
settin the sub-woofer system ri ht next to standard speaker
system. Adjustment may be required dependin on the
positionin of each unit.
3. Since the level settin 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 accordin to the location
and condition of the area in which it is used.
