WIDE-DISPERSION
CEILING SPEAKER
SYSTEM
Delivering a new level of audio perfor
TOA introduces a new range of ceiling-mounted speakers
that have been designed and engineered to overcome
some of the limiting factors that have been associated
with conventional ceiling-mount speakers. Most noticeable has always been the high-frequency rolloff that
resulted from limited speaker dispersion characteristics.
TOA's new ceiling speaker range provides well-balanced
audio reproduction without treble attenuation over an
expanded listening area thanks to the extra-wide dispersion characteristics that are part of the overall speaker
design. Perceived speaker directionality and beaming tendencies are minimized, resulting in a natural, well-balanced sound over a wide area at all levels. Conventional
speakers exhibit high frequency rolloff characteristics as
the distance between speaker and listener increases.
However TOA believes that an ideal ceiling-mounted speaker's response characteristics should include wide dispersion and non-frequency dependent directionality and this
new ceiling speaker series proves that.

Detailed System Features
•Designed to blend into ceilings with a smooth,
low-profile design.
•Extra ease of use and higher cost-effectiveness with
the metal "back can" enclosure for the speaker rear.
(F-122C, F-2352C, F-2852C, F-2322 models)
•F-122C arouse increased speaker response control with
optional Equalizing Speaker Controller (A-120).
•Minimal high frequency rolloff allows clear and wellbalanced sound reproduction over a wide listening area.
Expanded listening area coverage thanks to the
extra-wide dispersion characteristics of TOA's
ceiling speakers makes it possible to utilize
fewer speakers to cover a desired area,
allowing more cost-effective installations.

Wide-Dispersion Ceiling Speaker Series
F-2852C (60W)
F-122C (30W)
Designed for higher power (60W) applications
in locations having higher ceilings that are in
the range of 3 to 6 meters.
Optimized for use with the optional A-120 Equalizing
Speaker Controller to deliver the highest quality audio in
ceiling-mounted speakers as well as to tailor speaker
response to suit specific installation requirements.
F-2322C (30W)
F-2352SC (6W)
A cost-effective full-range speaker that is ideal
for most ceiling sound requirements.
Perfect for low power use, this speaker has increased
cost-effectiveness and includes a metal "back can" for
greater installation ease.
F-2352C (30W)
F-1522SC (6W)
Standard 2-way ceiling speaker for applications
requiring a full range frequency response.
Special compact model designed for low output
applications .
