  • The Control 26-DT is a compact ceiling speaker assembly configured to install

    into standard ceiling backcans designed for 200 mm (8 inch) speakers. High

    power handling, wide frequency response and low distortion make the Control

    26-DT ideal for sound systems requiring a higher fidelity sound, that integrates with many backcan designs.

    * Transducer, Network and transformer.

    * Fits standard backcans for 8-inch speakers.

    * Wide coverage.

    * Advanced crossover network provides even coverage throughout listening area.

    * 60 Watt transformer for 70V or 100V lines.

    * Coaxial 165 mm (6.5 inch) woofer with butyl rubber surround and 19 mm (¾ inch) titanium coated tweeter.

    Full range compact ceiling speakers. Low distortion and a smooth, natural frequency response make the Control 24CT Micro ideal for medium volume business music systems as well as for the medium to low SPL segments of larger or louder systems.

    The Control 24CT Micro includes a multitap transformer for 70V or 100V systems.

    • 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.
