What effect does the size of the top plate on a speaker stand have on
the sound. I am looking at some stands where the top plate is
somewhat smaller than the speakers footprint so some of the speaker
will hang over the edge of the stand.

As long as it's big enough to support the speaker, no difference at
all. Though I'm sure you could ask elsewhere and get some audiophool
pseudo-science to suggest it did :-)
