I'm trying to build the large square horns to replace the YL Acoustic MB90's I have now.
Are there plans anywhere? I know I could use a calculator, but I thought I try for already published plans first.
Send me a message to :
replacing the X by the arobase.
So I'll send you the Version of my excel spreadsheet that give the planar cuts of one facet of a horn made using facets (gramphone style).
Also I'll send you an excel spreadsheet to calculate the adaptor from a round compression driver outlet to square (in fact it allows "round to rectangle" adaptation).
