TOA bs-1030 Installation Instruction

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.
