Thank you for purchasing TOA's Subwoofer System.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.
• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions
regarding safety.
• After reading, keep this manual handy for future reference.
WARNING
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
• Refer all installation work to the dealer from whom
the speaker was purchased. Installation for flying
requires extensive technical knowledge and
experience. The speaker may fall off if incorrectly
installed, resulting in possible personal injury.
• Flying Precautions
Be sure to follow the instructions below. Otherwise,
the suspension wires or belts may be off or snap
and the speaker may fall off, causing personal
injury.
· Check to confirm that the suspension wires and
belts are strong enough to withstand the speaker
load.
· The connectors of the suspension wires and belts
must be securely linked with those of the speaker.
· All parts and components (such as enclosures,
metal pieces, and screws) must be free from any
deformation, crack, and corrosion.
· Be sure to use screws supplied with the optional
flying hardware when installing the speaker using
such hardware.
• Install the speaker only in a location that can
structurally support the weight of the speaker and
the mounting bracket. Doing otherwise may result
in the speaker falling down and causing personal
injury and/or property damage.
• Since the speaker is designed for in-door use, do
not install it outdoors. If installed outdoors, the aging
of parts causes the speaker to fall off, resulting in
personal injury.
• Owing to the speaker's size and weight, be sure
that at least two persons are available to install the
speaker. Failure to do so could result in personal
injury.
• Do not use other methods than specified to install
the speaker. Extreme force is applied to the speaker
and it could fall off, possibly resulting in personal
injuries.
• Use nuts and bolts that are appropriate for the
ceiling's structure and composition. Failure to do so
may cause the speaker to fall, resulting in material
damage and possible personal injury.
• Tighten each nut and bolt securely. Ensure that
the bracket has no loose joints after installation
to prevent accidents that could result in personal
injury.
• Do not mount the speaker in locations exposed
to constant vibration. The mounting bracket can
be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
• Avoid installing the speaker in indoor swimming
facilities that are not well ventilated. In such
locations, the mounting hardware may be vulnerable
to corrosion, eventually allowing the speaker to fall
resulting in personal injury.
CAUTION
• Avoid touching the front punched net's sharp metal
edge to prevent injury.
• To avoid electric shocks, be sure to switch off the
amplifier's power when connecting the speaker.
• Do not place heavy objects on the speaker as this
may cause it to fall or break which may result in
personal injury and/or property damage. In addition,
the object itself may fall off and cause injury and/or
damage.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property damage.
• Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker or its
mounting bracket that could cause the speaker to
fall, possibly causing personal injury.
• Do not operate the speaker for an extended
period of time with the sound distorting. This is an
indication of a malfunction, which in turn can cause
heat to generate and result in a fire.
2. GENERAL DESCRIPTION
The FB-150B and FB-150W are compact, indoor-use subwoofer systems, each employing a high-power 38 cm (15") woofer.
They are designed for use in conjunction with TOA's HX-7 Series Speaker System or other full range speakers, and are
particularly ideal for reproducing dynamic low-frequency sound.
The FB-150B and FB-150W can be suspended by wires or chains with use of an optional HY-PF7B or HY-PF7W Speaker
Rigging Frame.

4. Input Connectors
• The NEUTRIK Speakon connectors are internally
connected in parallel to the screw terminals; you can use
either one.
• Two Subwoofer Systems can be operated in parallel by
connecting them in a cascade configuration as shown
below.
• The table below shows the pin arrangement of the
Speakon NL4MP connector.
Note
Be sure to connect the Subwoofer System to the power
amplifier's output terminal of 4 Ω or less.
Connecting it to an output terminal of over 4 Ω may cause
amplifier failure.

5. INSTALLATION
The Subwoofer System can be installed on the floor or can be suspended from a ceiling, etc. When suspending, use the
optional HY-PF7B or HY-PF7W Speaker Rigging Frame.
WARNING
• Use the suspension wires, chains, and anchor shackles that are
strong enough to withstand the total weight of the speaker and
mounting hardware.
Failure to do so may cause the speaker to fall, resulting in personal
injury.
• Owing to the unit's size and weight, be sure that at least two
persons are available to install the unit. Failure to do so could result
in personal injury.
For installation method, refer to the instruction manual supplied the HY-PF7B or HY-PF7W.
6. EQUALIZING BY DIGITAL SIGNAL PROCESSOR
When using the FB-150 Series Subwoofer System in combination with the TOA HX-7 Series Speaker System, it is
recommended that the TOA Digital Signal Processor (DSP) be used to set the recommended parameters.
For setting, refer to the HX-7 Series instruction manual.
7. Level Balance AND Polarity
When using the FB-150 series in conjunction with full range speakers (such as TOA's HX-7 Series Speaker System), adjust
the level balance and polarity for each speaker independently depending on the installation site.
[Level balance adjustment]
Increase or decrease the level of the subwoofer (or full range speaker) as appropriate to the number of units and installation
conditions.
[Polarity adjustment]
• If the subwoofer and full range speakers are in phase in their crossover band, then acoustic energy is added; however,
acoustic energy is subtracted if the two are in reversed phase. Since the phase characteristics of both the subwoofer and
full range speaker change continuously depending on the frequency, it may not be ideal to follow the subwoofer's polarity
instructions when connecting it.
• Compare the degree to which acoustic energy increases by switching the polarity of the connection at the subwoofer
(from positive to negative and from negative to positive). Choose the way of connection that results in the greatest
increase in acoustic energy. To match the polarity correctly, make actual measurements of acoustic energy using a real
time spectrum analyzer.
