I don't think Steve "bought into" the conical propaganda, more that it is easier for him to make conical horns and get a system up and running. So this is by no means finished. We have discussed him trying some different profiles (Le Cleac'h) for the...

First let me say I am NOT trying to promote the Synergy horn. I just think it is very intresting to look at and to think about.Ideal loading only occurs at a singular frequency within any horn. This ideal loading point is where the length is 1/2 a wa...

My view of the whole system is:
The Horn is conical, defined by the 3 intersecting walls (a pyramid with an isosceles triangle as base).
