This hall offers seats to an audience of 352 persons and is decorated with light wooden panels, the reverberation being quite neglectable. For the construction of the scaffolding, the seats will be removed, allowing a seating position more suitable to the sound dome. The scaffolding will sustain the ensemble of 104 loudspeakers, distributed according to the well-calculated plans by the project designers. As the loudspeakers are three- and four-way constructions, the total amount of speakers will be about 350.
Within a sound dome the best listening places are theoretically rare. They are at the focus of the dome. To avoid limiting the project to an elite of listeners, we have designed the dome's center as large as possible. A distance of at least 10 meters must separate the listener from the loudspeakers, in order to make the sound sources change in permanent movement (in the case of kinephonic music) without tiring the listener fixed in one place. The real center of the dome is a little below the horizontal line of the floor, allowing to enlarge the sound dome and to let more listeners benefit of the ideal listening zone. Considering the trapezoidal shape of the hall, we decided to make an egg-shaped dome, well adapted to the proportions of the hall.
