Thank you for your kind comments,
I am well aware of your beautiful system.I wonder how many times I have read that inspirational article on the Belgian Audiophile School site.Particularly the 3 dimensional curves of your basshorns is to he much admired although myself,the architect, structural engineer and builder involved all shied away from such awesome complexity and opted for a much simpler shape with only a 5 degree slope in the roof of the horn.
Still yours must be the ultimate expression of what can be done.In the end we achieved a 0,5 cm tolerance in the basshorn but it took some really fine plastering.How you achieved that with naked brick is mind boggling.
Your work as well as that of M
Rogerro has served as inspiration in creating this and although I have never met or corresponded with either I salute you and Monsieur Rogerrro for your willingness to publish and so share your secrets .Also people like Karel Schees (Carolus here) who freely shared their experience and expertise.The horn world is small and the mega-horn world miniscule.The fact that much of it is locked away behind the barriers created by Japanese script and language (Thank goodness for Jean Hiraga) and to a lesser extent French makes navigating these waters all the more challenging With gratitude
