David, As a 1954 SSL is in my shop next in line for restoration I am most interested in your design. Would you be so kind as to explain how you measure and quantify impedence?

Don't know how much of this will come through but here's an example of a modified L scale with a 5 note transition bridge that I'm playing with. You can see the shape of the bridge by the purple line showing the speaking lengths, the five note transition is seen where the drop in inharmonicity is. The goal is balancing tension (red), impedance (grey) and inharmonicity. The blue line at the bottom indicates break point %. Now to see how it will sound.
