I ordered a top cover and bottom pre-cut foam from Edwards. If I had to do this over again, I'd buy a sheet or two of acoustic foam, and cut it to fit the piano.  That's all the bottom foam is from Edwards.  And the top piece has the same type foam with a cloth cover.  Granted, it's custom-fit to the piano, which is nice.  But quite expensive.  Seems like the pre-cut foam was $110 (for a Yamaha G1). Three or four pieces that wedge in between the beams.  Easily done for less on the bottom pieces with a sheet of foam and a sharp knife.  </DIV> <DIV><BR></DIV> <DIV>That, along with voicing, made the customer very happy.</DIV> <DIV><BR></DIV> <DIV>I remember from my Googling "acoustic foam" after that experience, that there are different grades of the stuff.  More dense, more reduction.</DIV> <DIV><BR></DIV> <DIV>--</DIV> <DIV>JF</DIV> <DIV><BR></DIV> <DIV><BR><BR> <DIV class=gmail_quote>On Tue, Oct 28, 2008 at 9:31 AM, Tom Driscoll <SPAN dir=ltr><<A href="mailto:tomtuner@verizon.net">tomtuner@verizon.net</A>></SPAN> wrote:<BR> <BLOCKQUOTE class=gmail_quote style="PADDING-LEFT: 1ex; MARGIN: 0pt 0pt 0pt 0.8ex; BORDER-LEFT: rgb(204,204,204) 1px solid"> <DIV bgcolor="#ffffff"> <DIV><FONT face=Arial size=2>List,</FONT></DIV> <DIV><FONT face=Arial size=2> Problem :</FONT></DIV> <DIV><FONT face=Arial size=2>Apartment dwelling piano performance major with a small grand is getting complaints from the neighbors .</FONT></DIV> <DIV><FONT face=Arial size=2>I can't find any info on sound reduction materials designed for the piano.</FONT></DIV> <DIV><FONT face=Arial size=2>Did Edwards have some products ?</FONT></DIV> <DIV><FONT face=Arial size=2>Thanks.</FONT></DIV> <DIV><FONT face=Arial size=2>Tom Driscoll</FONT></DIV></DIV></BLOCKQUOTE></DIV><BR><BR></DIV></DIV> <DIV class=aol_ad_footer id=MAILCIADB012-88ad4907e1632f5><BR><FONT style="FONT: 10pt ARIAL, SAN-SERIF; COLOR: black"> <HR style="MARGIN-TOP: 10px"> </HR>McCain or Obama?
