Two things are striking to me:
- The pipe organ is absolutely exceptional, the only instrument whose fundamental frequencies cover the whole bandwidth.
- They define bass frequencies up to 250 Hz, very high, so that low female speaking voice is still in the bass register... (which is true of Gillian Anderson's German dubber in the X Files of course, but...)
