The organ is positioned about 5m below the entrance, which was important both for the case design, its proportions (taken out by Simon Platt) and the voicing.
The intensity of the sound is very different from the keyboards or in the audience. The only resonating structure of this room is the case (the panels of ceiling and walls are of materials with surfaces partly sealed ).

Taking into account these circumstances we have chosen a wind pressure of only 55mm WG. The pipe shades are completely closed. The difficult struggle between evenness and vitality was often sorted out in favour of the natural pipe speech and sound.
