Hi Bonnie. Here is are a couple of clues to find those spreadsheets on the
net. One of the text files with these programs has the following addresses:
Brian Steele (brian@caribsurf.com)
or: http://ourworld.compuserve.com/homepages/Brian_Steele/4thorder.htm
There is another alos that finishes.....6thorder.htm
I think you'll find these spreadsheets very useful and they appear to be
based on simple and sound engineering principles. I have used them to
modify my guitar amp's enclosure and got about 6 dB more base @ 80Hz. I was
thinking of posting my copies to this BBS but it is closing next month and
the sysop probably doesn't want more clutter. I hope this helps... Geoff
