1 WIDE-DISPERSION FLUSH-MOUNT CEILING SPEAKER F-282C F-2322C F-232C F-22C F-232SC F-22SC 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 listener increases. However TOA believes that an ideal ceilingmounted speaker's response characteristics should include wide dispersion and non-frequency dependent directionality and this new ceiling speaker series proves that. 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-22C, F-232C, F-282C, 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-2) option is required to provide increased control of the F-22C's speaker response.
