Subject:Re: 145 vs 147

Simple. The two interact as the sound emanates from the louvers and back. Right? The closer the top rotor's sound is to the lower rotor's makes a difference. A tall boy leslie as in a 30A will definitely have a different sound compared to a closer rotor spread 122, 145 or a 222 which has both rotors on the same plane with the bass cab above them both.. The same difference would happen if your stereo speaker's tweeter were a foot away from it's woofer...

What do you mean by "the wash of each rotor interacting with each other"? The output from my upper rotor on my 145 is pretty much isolated from the middle cavity and lower rotor space.
