[sdiy] Simple discrete Unity-Gain Follower ?

[Czech Martin]

Right. The idea to have motional feedback on speaker cones
is not that new, the first paper about that I have seen from
1970 or so. All mentioned problems of servo loops apply,
also the strong forces on the cone due to servo action can
produce partial oscillations of the cone...
a unique "feature" of speakers...

m.c.
