Designed to ‘blend’ into the ceiling, this range has smooth, low-profile design, and extended dispersion to give reduced high-frequency attenuation when off the main axis of the speaker, for reduced ‘beaming’ and better balanced reproduction and hence clarity.
All the models are natively eight ohms impedance, but are fitted with a transformer to provide 16 ohm and high impedance 70/100V line connections. The impedance/power setting can be achieved from below the speaker after it is fitted in the ceiling; the grille is removed with a twist, revealing the face of the speaker with a rotary selection switch. Baffles and rims are fire-resistant ABS, the grilles are punched steel plate, finished in white.
Intended for use in ceilings from two to four metres high, these have no back-box, but are fitted with a dust-proof bag. The terminals are of the push-in type, with extra terminals for looping connections to the next speaker. Can be used with HY-BC1 back can.

Accessories
HY-AH1 Anchor Hanging Bracket
A yoke bracket to suspend speakers from an anchor bolt, to avoid the full weight of the speaker being applied directly to a ceiling panel. It works in conjunction with the hardware supplied with the speaker. Plated steel. 700g.
A metal can for attachment to the ceiling speakers to present a better appearance when they are mounted in view, thus forming a pendant speaker. It has a central ‘knockout’ hole to match 20mm/28mm pipes, from which it is usually hung, and a further two 20mm ‘knockout’s . Steel plate, black paint, 1.5kg. Fits F-2352SC, F-2322C, F-2352C.
HY-TB1 Tile-Bar Bridge
Working with the hardware supplied with the speaker, this is a pair of bars which transfer the weight of the speaker from the ceiling panel to the ceiling grid. Plated steel, 603mm long, 500g per pair.
A cosmetic ring which will allow the installation of 200mm mounting speakers into holes which are oversized, up to 300mm diameter.
Technical Note:
An ideal ceiling loudspeaker would radiate all frequencies at an equal level, regardless of the angle off-axis. Unfortunately there is no such thing as an ideal ceiling speaker. This series of speakers approach the ideal more than many, with the consequent benefit that speakers may be more widely spaced for equivalent performance, or alternatively, if spaced the same as more conventional models, will give improved sound quality and hence clarity of announcements and music.
