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 two 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 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 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 wires 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 dividing network, detach the terminal panel at the back of enclosure and mount the dividing 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.
