That's not true. Both affect the sound throughout the room but
differently.

Yes, both statements were over-simplifications. However the pervasiveness of
electrical changes is far greater for pretty obvious reasons. One usually
only has to experiment with acoustical treatments for a little while before
one finds that there are parts of the room where the effects are global, and
other places where they are frustratingly local.
