When we get a ping or a bite to the tone from keytop then isn't that primarily exciting the higher partials rather than the fundamental? >> I think the power comes from the fundamental, and perhaps the next two or three partials. HOwever, without the higher ones, our ears don't sense it. It was really enlightening when I bought a pair of L110's (JBL speakers) at a garage sale for $20. I got them home and hooked them up and was amazed at how little sound I was able to get from them with a 100 watt rms amp. Then I realized that the mid-range and tweeters were burned out. With almost full power, they didnt' sound very loud or powerful. After sending them back to JBL for new cones in the tweeters and mids, I re-installed them and at 1/2 power they absolutely blew me out of the room! Our ears need the higher partials to sense loudness and power. The same is true of hammers. A set of rock hard hammers may seem to be really loud on the stage, but without resiliency in them, they sound thin and harsh out in the hall. It takes a balance to really speak and project. I suppose you have a dead soundboard, but it would be a simple matter to take a hammer from a good sounding grand in install it on this piano to see...
