One has to force them down considerably. It may be that when that occurs the middle of the board is being forced down too. Is that bad.  I dunno.  But on One A-2 I did in the above fashion seemed to have a considerable freedom to the sound. It was different.  That's my subjective opinion. WHen I dropped the board it in the piano the first time it fit all the way round with little bass treble strain.</EM></STRONG></DIV> <DIV><STRONG><EM>     I have had the luxury & priveledge of hearing approx. 99% percent of the 100 or so boards I've installed so when something changes I pay attention.
