[Elecraft] Speaker SP3 Video

[Steve Ellington]

Yes, using a sound pressure meter I can see a peak around 570 and one down
around 330 or so . These are only about 3 db variations however.
Setting the speaker on the desktop makes a *HUGE difference* in
loudness...Maybe 10 db or so. The reflection from the surface helps greatly
and this is true of most speakers. Setting it on a shelf totally wrecks
everything.
