There are many books written on pipe construction, some very technical. Take a look at the Organ Historical Society Website, www.ohscatalog.org. They have quite a few books available on-line. You might want to call them for a recommendation.
A subbass is a foundation flue stop usually found in the Pedal Organ. Typically, it is a 16' stop which produces a 32Hz frequency at Low C. The Posaunen is a reed stop sounding like a Trumpet or Trombone in the lower registers. At 32' a Posaunen will have a relatively weak fundamental frequency at 16 Hz, Low C. But the beating of the reed at this frequency provides power to the full ensemble or "full organ"
I haven't heard this CD but it sounds like a small scale organ, voiced in the Northern German style. Clarity of tone is more important here than really deep bass, especially for contrapuntal music like that of Bach.
I found real inspiration while listening to organ recordings and then listening to organ music. The clincher for me was music from the French Romantic Period of the 19th century (Franck, Widor, Guilmant, Vierne). Big sound, large instruments, and glorious music. Not very popular though!
