On the portable side, here’s a nice video of the Elkatone 610, which I use if I want to bring a ‘Leslie’ out. Not quite the real thing, but spins the air just fine, and gives a much better 3D-effect than most simulators, especially the high rotor works very well. Crossover is different, and the lower speaker gets the full signal. Fits into the boot of my car, and works well with the hot output of a Nord C1.
