This is interesting! Can you give more details, such as makers, approximate dates, and what they tried? Which ones had the double soundboards? How far apart were they? How many posts were used, and where were they placed? Most importantly, did they work in improving the tone? That is, were they discontinued because they were too expensive to produce, or because they didn't give the desired results? Do you know of any written materials such as books or articles about these pianos? >As for prior art, there have been a couple piano patents mentioned here that >seem to have precedent (S&S, B). Maybe M&H could add springs between the >tension resonator and sb really to make that thing sing ;) <grin> seems to me that they sing already, and keep singing even when other things like the pinblock and hammers are on their last legs.
