When Installing the Unit
• Install the unit only in a location that can
structurally support the weight of the unit and the
mounting bracket. Doing otherwise may result in
the unit falling down and causing personal injury
and/or property damage.
• Do not use other methods than specified to mount
the bracket. Extreme force is applied to the unit
and the unit could fall off, possibly resulting in
personal injuries.
• Use proper nuts and bolts when hanging the
speaker. If improper nuts and bolts are used, the
speaker could fall off, resulting in 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.
When the Unit is in Use
• Do not operate the unit 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 TOA FB-100 is a high-power sub-woofer system employing a 25 cm speaker unit designed to withstand
large, low-frequency voice-coil movement. Although small in size, the FB-100 provides clear super-low
frequency sound reproduction thanks to its Acoustic Super Woofer enclosure construction.
3. FEATURES
• A large, 120 mm-diameter ferrite magnet, a long, 50 mm-diameter voice coil, an aluminum bobbin, a nonpressed paper cone, and a large-diameter damper combine to permit large voice coil movement at high
power input.
• The Acoustic Super Woofer system enclosure creates an acoustic band-pass filter that reproduces superlow frequencies down to 35 Hz and realizes slow-slope phase characteristics.
• The speaker can be converted to high-impedance applications with the addition of the optional MT-S0610
matching transformer.
• The urethane-painted enclosure is made of Medium Density Fiberboard (MDF) and can be easily repainted.
• Six external mounting screws are positioned along the sides of the enclosure to facilitate cable-suspended
installations.
• The unit's removable top panel facilitates maintenance work after installation.
4. HANDLING PRECAUTIONS
No anti-magnetic provisions have been made for the FB-100 speaker. Therefore, take care to keep the unit
sufficiently away from televisions, monitors or computer-related equipment.
