"Statistically" you are correct. But maybe if any
Hammond/leslie techs are lurking around, you could
chime in on this. I've been told by 3 different techs
the same thing: the majority of your sound comes out
of the upper rotor. It's common knowledge that lower
frequencies require more power; it's also common
knowledge that lower frequencies require faster
speakers (being a bassplayer as well, I can testify to
the fact that a sluggish speaker will give you dogsh$t
tone...and being a BASS player, you don't have the
luxury of letting the upper end stuff carry you).
However, the 15" speaker put in leslies aren't exactly
known for their high performance (although they work
and sound great in this application). Regardless of
the power distribution, the "fact" remains (at least
as far as I can tell, and what I've been told) that
most of the sound comes from the upper horn. That's
not to say that low end is not important; quite the
contrary.

Regardless, we both agree that the lo-pro is a
necessity for satisfaction (mine anyway) from the 3t.
