2 recordings of: Ich ruf zu Dir, Herr Jesu Christ BWV 639.
The stops used are Silbermann only.

First:

Ped: Subbas 16'
RW: Bourdon 8'
HW: Montre 8'

Second:

Ped: Subbas 16'
Octavbass 8'

HW: Montre 8'

RW: Bourdon 8'
Prestant 4'
Nazard 2 2/3
Doublette 2
Tierce 1 3/5

Both choices work well imho, though in the first you miss the couple of RW to Pedal.

But that's how the organ is constructed and the Subbas carries well enough.
