- 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 roll-off 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 roll-off 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.
- 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.
- Minimal high frequency roll-off 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.
