 Hello,

As I don't have myself any website and as I couldn't find any place on the web to put the english version 2007 of my spreadsheet the best thing is to send me your email adress at both:

lecleachXcgi.ensmp.fr and lecleachXmusee.ensmp.fr

and I'll send you the new version of the spreadsheet for which the step by step estimation of the curvilinear length of the wavefronts has been improved. (using the spreadsheet one can compare the "new" profile and "old" profile).

Also, the version 2007 of the spreadsheet allows the calculation of "gramophone style" horns having any number of facets (4 for a square horn). It give the coordinates of points of the curves you then have to cut inside a plywood or metal sheet before to curve and assemble them "edge on edge".

You have to know that David McBean's excellent software "HornResp" allows the calculation of horns according to the same improved method as in my spreadsheet version 2007. Within HornResp when the window shows the "schematic diagram" you can export the profile.

Best regards from Paris,

Jean-Michel Le Cléac'h

P.S.: At the end of the week, I'll give a "conference" about axisymetrical horns with a special interest to simulation under "Hornresp" during ETF'07 (European Triode Festival 2007) in Biezenmortel, the Netherlands (Holland): http://www.triodefestival.net/




Best regards from Paris

Jean-Michel

 Jean-Michel himself recommended HornResp in 2007, and it's been vastly improved since then.
