I have read that there is a flaw in his spreadsheet so research it here. Please post yoru findings.

I also attached the original article from the 1980's by Edgar.

From what I am learning, you need to use an Fc of about 250 hz to 300 hz to make these horns work correctly. Are Al's horns designed with an Fc in this range? They seem kind of small if they are. I came up with an 18" x 12" horn using 250 Hz.
