In the new series of videos “[un]seen spaces” we’ll present you details of the Philharmonie Luxembourg that you probably already have seen, but never really perceived. I imagine this might be the case with the three-part adjustable sound reflector in the Grand Auditorium. Situated above the stage, this reflector diverts sound towards the audience and ensures the musicians hear themselves perfectly.
You see, it plays an essential role in the acoustics of the hall and it is very important to adjust it to the type of musical work played on stage. Within the last 8 years, we have determined various positions in order to get the best possible sound in the Grand Auditorium, which goes from the highest position for organ concerts to the lowest position for piano recitals.
Some key figures:
each ceiling is 16,7 m large and 3,2m wide.
each ceiling weighs 5,5 tonnes – the whole reflector weighs approximately 16,5 tonnes.
each ceiling is run by 4 engines and each engine moves/runs 3 steel wires (12 steel wires pro ceiling). The left and the right engines (front and back) run synchronously, in order to prevent any side inclination of the ceiling.
