When you have a closed end duct or horn and the source is between the open end and closed end, there is a reflection from the closed end back to the source. When that reflection traverses 1/2 wavelength or multiples of that, there are cancellation notches in the response as the sound arrives delayed 180 degrees (or multiples). One see's the same thing in the ,id and low frequency portions of the Synergy horns and the first notch must be above the highest frequency your using that portion to.
hope that helps
Best,
Tom
