So to understand this, do you want a smooth horn path? Lately it seems that guys that have access to CNC machines are going for the layered look. So is it worth doing a smooth horn path or is the standard horn path out of straight panels just as good. The reason I ask is I am wanting to build the Dallas II speakers. I have had some 206e drivers sitting hear for a while. I modeled the speaker from the plans on Dave's site and there was only one dimension I was missing to have everything match the dimensions from the plans. I guessed on it and I think I have come close but anyway I also created a curve in the model to show a smooth horn path. I was going to build it using this smooth path. So I guess I am asking if its worth it to do the smooth path or if the path using straight edges is as good.

John, if you look at the Dallas II photos, the kerfboard implementation would not be hard to build. But if you don't want some curved exterior features, the square build only requires adding three curves. This shouldn't change dimensions.

I'm a bit confused by Ron's water analogy. The analogy to water is air, not sound. Is it safe to assume sound waves behave the same as flowing fiuids and gases?

Also, I did read a comment from RonC that the Dallas II does does not incorporate his latest design thinking. Sorry, I didn't think to save the link.

There are a lot of designs of back-loaded horns like the Dallas. It might be worth looking at the most developed. Or use the available tools to rerun the numbers on the Dallas.
