Subject:Re: Motion Sound: matching upper/lower rotor speed


The opposite direction of the Leslie rotors was not a design flaw,
that's the contrast! That makes the Dopler Effect even more audible.
The reason they rotate opposite is because the top rotor motor is
placed underneath the rotor and the bottom one is upside down, above
the bottom rotor. Therefore, they spin in opposite directions.
