FEATURES

WIDE-DISPERSIONFLUSH-MOUNT CEILING SPEAKER

●

●

●

●

●

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 well-

balanced 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.

DESCRIPTION

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 listenerincreases. 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.

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.

OPTIONS

Unit: mm

The HY-BC1 Back Can is a metal case attached to flush-mountceiling speaker when mounted in exposed applications. The BackCan is hung from a ceiling suspension pipe.

The HY-TR1 Trim Ring allows installation of flush-mounted ceilingspeakers in pre-existing ceiling panel holes which are over 200mmin diameter. The use of 2 Trim Rings allows the speaker to bemounted in holes from 240mm to 300mm in diameter.

The HY-TB1 is channel bar to be used when supporting flush-mounted ceiling speakers by way of ceiling bars to prevent their fullweight from being directly applied to the ceiling panel duringinstallation. This channel bar is used in conjunction withreinforcement hardware supplied with the speaker. One complete setconsists of 2 HY-TB1 bars.

The HY-AH1 Anchor Hanging Bracket is designed to support ceiling-suspended speakers from an anchor bolt in order to prevent thespeaker's full weight from being directly applied to the ceiling panel.It is used in conjunction with reinforcement hardware supplied withthe speaker.

The AC-120 is a controller for F-122C, F-121C/121CM or F500,600 series.
