## **Teatro Comunale di FirenzeFlorence, Italy

The mobile concert shell of the Teatro Comunale was developed according to the specifications
of the acoustician MBBM. The special feature of the concert shell is the ceiling,
which consists of a single piece and measures 17 x 10 m. For storage, the ceiling
is placed in its entirety on trolleys, moved to the rear and hung vertically in 
a parking position.

## **Teatros Del CanalMadrid, Spain

The DIVA Concert shell by Wenger transforms the theatre into a concert hall in no
time. Consisting of nine towers of different heights and four ceiling sails, the
sound is directed undistorted into the auditorium. Remarkable is the choice of colours,
here executed in red.

## **Bühnen BernBern, Switzerland

The Concert shell in Bern is a masterpiece in terms of acoustics and technology.
We manufactured the concert room according to the specifications of the MBBM acoustics
office. The 6.5 m high x 2 m wide towers can be flexibly assembled and later stored
horizontally in the container. The same applies to the ceiling canopies.
