Delivering a new level of audio perfor
TOA introduces a new range of ceiling-mounted
speakers that have been designed and engineered to
overcome 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-2322C models)
• Minimal high frequency rolloff allows clear and wellbalanced sound reproduction over a wide listening area.
• Quick and easy installation to precisely mount speaker
onto ceilings and walls. Rotating front grille also installs
quickly and conveniently.
• The Electronic Controller (AC-120) option is required
to provide increased control of the F-122C's speaker
response.
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.
