For those of you who own Wurlitzer style A, D, AX or DX instruments
with the pipes behind the sounding board, as opposed to those who own
BX or CX with the pipes on inside:

What is the difference in volume of the pipes in both situations?
Are they more muted inside rather than being behind the instrument,
or vice versa?

Does anyone have any general comments regarding pipes placed behind
the sounding board?

Cheers,
Stephen Kent Goodman
