DESCRIPTION
TOA’s F-240 and F-160 Series of foreground/back-
ground music speakers are ideal for applications
requiring both sonic quality and designer styling.
These two-way, ported systems provide a wide fre-
quency range and high power handling capacity-
in an attractive, acoustically-efficient polypropylene
enclosure.
Each of the F-240 and F-160 Series includes four
models-two dark gray and two white, indicated by
the suffix “G”or “W”. Models with the suffix “GM”or
“WM”include a built-in 70/100 volt matching trans-
former. In all, eight models are available to match a
variety of job requirements.
The F-240 Series features a
6"/4" woofer and a 1"
titanium dome tweeter, which includes an acoustic
equalizer and a 90" x 90" CD horn for uniform sound
distribution at high frequencies. Frequency response
is 65Hz - 20kHz, with crossover at 4kHz. Sensitivity is
rated at 92dB (1W/1m).
The F-160 Series features a 5" woofer and a 1"
dome tweeter, which also includes an acoustic equal-
izer and a 90" x 90" CD horn. Frequency response is
100Hz - 20kHz, with crossover at 4kHz. Sensitivity is
rated at 91dB, measured in whole-space (1W/1m).
Both the F-240G/W and F-160G/W feature a continuous
pink-noise power rating of 50 watts at 8
Ω , and a con-
tinuous program power rating of 150 watts at 8
Ω. Built-
in protection circuitry guards all components against
overloads.
The F-240 and F-160 Series are engineered to com-
bine maximum efficiency with a flat frequency response
when mounted in a half- or quarter-space environment.
The typical position for a foreground/background
speaker is against a wall or at the intersection of a wall
and a ceiling or second wall. This is the acoustical
environment for which the new F-Series is optimized.
The F-240GM/WM and the F-160GM/WM feature an
internal line matching transformer with four impedance
selections for 100 volt line and five selections for 70
volt line, adjustable via a rotary switch under the rear
cover. These four models each have five 70 volt trans-
former taps ranging from 2.5 watts to 30 watts.
All systems are easily mounted in vertical or horizon-
tal positions with a wide range of optional mounting
brackets, and a logo badge on the front grille rotates to
match the enclosure’s orientation. A rear cover with a
cable feed slot protects connection terminals.

The F-240G/W and F-160G/W shall have a continuous pink-
noise power rating of 50 watts at 8Ω and continuous program
power rating of 150 watts at 8Ω. All F-Series speakers shall have
push-type input connectors, and all 8Ω versions shall have pro-
tection circuitry to guard components against overloads.
The F-240GM/WM and F-160GM/WM shall have five 70 volt
transformer taps ranging from 2.5 watts to 30 watts. An internal
line matching transformer with four impedance selections for 100
volt line and five impedance selections for 70 volt line, adjustable
via a rotary switch under the rear cover shall be included.
The enclosures shall be made of acoustically-efficient
polypropylene, in gray (G-suffix) or white (W-suffix). All speakers
shall be easily mounted in vertical or horizontal positions, with a
wide range of optional brackets. The front grille shall have a logo
badge that rotates to match the vertical or horizontal enclosure

tems shall weigh: 10.8 lbs/4.9 kg. (F-240G/W); 12.1 lbs/5.5 kg.
(F-240GM/WM); 7.3 lbs/3.3 kg. (F-160G/M); and 8.6 lbs./3.9 kg.
(F-160GM/WM).
OVERLOAD PROTECTION
The F-240G/W and F-160G/W feature built-in over-
load protection circuitry. A sudden drop of either the
high or low frequencies during speaker operation
indicates the protection circuit has been activated.
After approximately 3 - 30 seconds, the system will
automatically reset itself. If the protection circuit acti-
vates again, reduce the system volume.
