Well, that is what most of this conversation has been about. 
 
At the time I was designing the 122 Fandrich vertical piano it seemed logical to me (and it still does) that it would be desirable to place the driving energy source of the vibrating diaphragm—i.e., the bridge—relatively close to the middle of the working part of the soundboard and its supporting ribs. The energy wave starts there and moves away from both sides of the bridge on across the soundboard to the mounting points and it seems a good idea that both arrive at more-or-less the same time. Since this was a new design and I could do anything I wanted I did so and was pleased with the results. It’s one of the best treble sections I’ve designed for any piano of any type. This was, to my knowledge, one of very few pianos that have been built with the treble section designed so the bridge could be placed relatively close to the center of the ribs. At least I can’t recall seeing any others. The physical construction of the grand piano makes it impossible and I don’t know of any upright piano designs that attempted it though there might well be some.
 
As may be, I got a combination of power and sustain out of this design that was noticeably better than anything I’d done previously. And this with relatively light and un-juiced hammers.

Yes indeed. Can you talk a bit about the treble bridge as well? Without your redesign work the bridge would also be located near the end of a rib – not so desirable up there.
