3. HANDLING PRECAUTIONS
Use optional mounting brackets when mounting the speaker to the ceiling or wall.
Avoid using the speaker on the beach because the speaker's life can be greatly shortened by sea breezes.
TOA takes no responsibility for any accident or equipment failure due to inadequate installation places or
incorrect installation methods or disassembly or modifications carried out for the purposes other than repair
service.
The F series speaker is not magnetically shielded. Install it as far away as possible from color televisions or
video monitors to avoid degradation in television picture quality.
4. FEATURES
Two-way bass-reflex system.
High efficiency, wide range, and high input power handling capacity.
F-160 series: High power capacity 13 cm woofer with a large 90 mm magnetic circuit, and high-efficiency
3 cm dome tweeter with a large 70 mm magnetic circuit.
F-240 series: High power capacity 16 cm woofer with a large 90 mm magnetic circuit, and high efficiency
3 cm dome tweeter with a large 70 mm magnetic circuit and a titanium diaphragm.
The tweeter employs a constant directivity horn which ensures uniform sound dispersion of 90 ° horizontal
and 90° vertical.
Independent built-in overload protection circuitry for woofer and tweeter. (Low-impedance models only)
A detachable rear cover cleanly conceals the speaker terminals.
Acoustically efficient polypropylene enclosure.
Optional wall and ceiling mounting brackets.
F-160WP: Drip-proof construction makes the speaker system ideal for outdoor use.
5. OVERLOAD PROTECTION CIRCUITRY INFORMATION
(LOW-IMPEDANCE MODELS ONLY)
The F-160G, F-160W, F-240G, and F-240W have a built-in overload protection circuitry.
If the excessive input is applied to a woofer or tweeter, the overload protection circuitry is activated and cuts
off the signal supply to the speaker component.
A sudden drop of the volume level of either the high or low frequencies during speaker operation indicates
that the overload protection circuitry has been activated. In such a case, reduce the amplifier volume and just
wait. The protection circuitry is automatically reset after approximately 3-30 seconds. After the circuitry is
reset, set the volume at a lower level than before.
[Important Note]
This overload protection circuitry does not perfectly protect the speaker component. Depending upon the
excessive input to be applied, the protection circuitry may not operate, causing damage to the speaker
component. In addition, the circuitry may not be restored to the previous state if the excessive input is applied
continuously for long time. Take special care that the excessive input is not applied to the speaker during use.

6. IMPEDANCE CHANGE (HIGH-IMPEDANCE MODELS ONLY)
Because the following models have a built-in matching transformer, connect them to the amplifier with a
high-impedance (70 or 100) line output.
F-160GM, F-160WM, F-160WP, F-240GM and F-240WM
Input impedance can be switched in five steps, as

shown in the table at right (factory-preset to 330
ohms). To change, set the rotary switch to the
desired impedance using a screwdriver blade.

When using the 100 line, never set the impedance to
170 ohms. The speaker itself or the power amplifier
may be damaged.
7. REAR COVER USAGE
F Series speakers feature a rear cover that cleanly
conceals the speaker terminals on the rear panel.
Cable feed slot
Rear cover
To remove the cover, insert a finger in the line feed
slot and pull the cover away from the speaker. To
reattach, simply snap the cover back into place.
F Series speaker
If required, the positioning of the cover's line feed
slot can be easily reversed by snapping the cover on
"upside down".
Speaker cable
Model F-160WP must be mounted with the line feed
slot facing down.

8. LOGO BADGE REORIENTATION
The speaker's front grille logo badge is attached with
double-sided tape. To change its orientation, carefully peel the
logo off the grille and stick it back on again in the same location
in the desired orientation.

9. OUTDOOR USE (F-160WP ONLY)
Model F-160WP can be permanently installed outdoors, and
other F Series speakers cannot.
Rear cover
In the F-160WP, the rear cover prevents water from getting
into the terminal section. When installing the F-160WP
outdoors, make sure that the rear cover is mounted with the
line feed slot facing down.
Speaker cable
The inside of the rear cover
If using a thicker speaker cable that does not easily fit through
the rear cover's cable guide, use a knife to cut out the rubber
cable guide along the imprinted groove, as shown in the
illustration at right.
[Note]
When mounting model F-160WP on the wall or under the
eaves, be sure to use optional outdoor mounting brackets.
Adjust the speaker installation angle and direction within the
ranges shown in the figures below:

Downward 60 °
Model F-160WP features drip-proof construction. However, do not dash water over it when cleaning as this
may cause damage to the speaker components.
When installing the F-160WP outdoors in a snowy area, protect the speaker by preventing snow from piling
up on it.
