Yea , i know what you mean Martin. TC and i have crossed swords several times.Just because you can sell something dosent mean its the best that can be done ie: B**e.
I use the basic old math and physics in my horns ,but i have learned to design for a given set of conditions so a universal horn IMHO is not really possible.
Actually one of the best i have designed and built was the Fe-103e horns that was very little more than a TQWT (conical flare) with a rapid expansion at the mouth, the mouth being designed for 1/4 loading (wall/floor). Not the most efficent but by far the cleanest bass i have made yet.Simple to build also.I actually had one guy get angry and claimed "it was some kinda trick" with the amount and clarity of the LF coming from such a weird design and with such a small (4") driver.Imaged like crazy too.

HI Roncla,
The project you describe sounds very interesting. Could you point us to a website that describes the project? Also, if we were to adapt the design for another similar driver, maybe you could give some poinbters on how to do that.
thanx!

Well its basically my design and as i have no website (too lazy) i really cant point you in a direction. I have today sent Jim an alternative to my complicated design, i call it the hedlund in a box which is a true horn and has an exponential/hyperbolic flare around M=.6. It was designed for the Fe-166e driver but i may be able to convert the basic design to the 206e.Send me an e-mail at roncla AT txucom.net and i will see what i have in my files for the 103e horn.
