Re: Hello to everyone old and new.

 

I witnessed it with my own ears. I put a sine wave tone at 600-700hz with the motors stopped and then physically reversed or flipped the phase of one of the drivers. It very easy to tell which way was in phase and which way was out of phase.?

Now, how much this affects the overall sound of the Leslie when motors are going fast and slow is debatable.?

Uwe,

I believe you are wrong in your claim, that "out of phase connection of both drivers will result in a considerable notch in overall frequency response in the xover frequency region".

This is a nebulous statement lacking any mathematical or scientific substance.?

You're absolutely right regarding the AC thing. But an out of phase connection of both drivers will result in a considerable notch in the overall frequency response in the xover frequency region. And, similar to a stereophonic setup, two Leslie's need to be connected in phase to get proper sound.
