Why not horns?

No matter what his rational for doing so what you have is an approximation of a horn. The reason for doing so is simple. It is much easier to make a wooden cone with flat panels than a true horn. From what I've read these compromises really become audible as frequency increases. I have no basis for this conclusion other than logic as I have never heard your cones, but if an approximation of a horn is good it seems logical that a true horn would be even better.

What's the price on yours? I can't get the link to work.

My horns are the AH 300. Price is around $2800/pr.

The link works for me. Go to the Acoustic Horn Company homepage. Then click on "How They Work". Then select "Conical Horn Geometry". That process will take you to the page I linked.

In this article, Bill explains his reasons (and how he reached them) for using the conical horn rather than something flared.

How do you determine what is a "true horn"? It would seem that you have set an arbitrary picture in your mind of what a horn is to the exclusion of any variant.

"Are you a cartographer?"

I am a software engineer with a background in digital cartography and related systems.

Is that for the horn or the horn + driver? If for the horn that's pretty expensive. You can get a solid wood horn from Jeffrey for a whole lot less.

I tried http://www.acoustichorn.com on 2 computers and can't get anywhere.

Not really. You can see from my system I have 2 variants. If possible I would have constructed the bass horn as a continuous flare but it would have been impossibly difficult. From what I am told by people who I trust a flare is better than a cone.. I am open to other possibilities.

I didn't say yours are bad, I simply suggested you might want to explore other possibilities. You seem a bit defensive.

Herman - I just clicked on the link in your entry above and it took me directly to Bill's homepage.
