Sonar Luna is a smooth black ceiling tile designed for areas that require good acoustics in dark surroundings like cinemas, concert halls, and night clubs. It is available with E or D edges for semi-concealed or concealed mounting. Sonar Luna with D edges is well-suited for cinemas as the grid is fully concealed, preventing screen reflections. The tile can also be combined with fiber optic accessories to create a starry night ceiling effect. When designing rooms with special acoustic needs, consulting an acoustic expert is recommended.

2. Sonar Luna
Sonar Luna is a smooth matt black ceiling tile that provides
a dramatic ceiling expression. It is the ideal choice for
cinemas, concert halls, theatres, night clubs and other areas
where good acoustics in dark surroundings are required.
Sonar Luna is available with both E edges for a semi-concealed ceiling
solution, and with D edges for a concealed appearance. Sonar Luna with
D edges is ideally suited for use in cinemas as the grid is fully concealed
thereby ensuring there are no distracting screen reflections on the ceiling.
Sonar Luna can be combined with RockLux Astro System, an accessory which
allows you to create the illusion of a starry night. The stars are formed by
integrated fibre optics – either 8 or 15 optics per tile. The integrated fibre
optics are protected by a solid cover on the rear of the tile.
When designing rooms which have special acoustic requirements, such as
cinemas, we recommend that you contact Rockfon or a specialist acoustic
consultant.
