A loudspeaker is suspended from each hub. Though LogiSon® loudspeakers are usually located above a suspended ceiling, we offer a range of models to accommodate your needs.

Ceiling Mount Adapter CMA-1

Ceiling Mount Adapter CMA-1

The Ceiling Mount Adapter is used when the LA-1 loudspeaker must be installed in gypsum or another hard ceiling material.

About downward-facing installation

A downward-facing loudspeaker (sometimes called ‘direct field’) is only used when installation conditions demand because the masking sound’s dispersion and uniformity will be reduced compared to an upward-facing loudspeaker.

If you prefer to avoid having the loudspeaker visible in the ceiling, in many cases the LogiSon hub can be connected to a transducer rather than to a loudspeaker. The transducer transfers the masking sound to the ceiling. Ask your LogiSon Representative for details.
