Re: when horn expansion and mouth size exceed the 1/4 lambda

For a single flare, small throat horn - more than likely a good recommendation, I know its been around since the early 1900's.

A pathway length of 1/4 wavelength of Fc is recommended for smooth response (less reactance variation caused by reflections from the mouth) in such a case. But it doesn't have anything to do with overall efficiency! That is determined by the throat.

Since the two (pathway length and throat size) are inextricably related, I suppose that is the crux of our problem.

I just want to point out, having a certain length pathway is not a requirement for good horn performance nor is it a guarantee that you will get the performance you intended.
