Jessie,
yes from a perspective of general horn propaganda your post it correct but from the perspective of “reading the back side of the midbass speed bump” I would argue that it has nothing to do with horn loading. Look at the notion widely. I would propose the following:
An abstract ultimate playback system MUST have a Midbass Channel that is driven by an amplifier with negative output impedance. The output impedance of the amp shall be equal to the impedance of the driver and the impedance of the amp shall cancel-out all mechanical influences that the driver diaphragm experience. I can invasion even two Midbass Channel - one with positive Z working on transient attack and one with negative Z working on decays. The negative output impedance for sure is not new subject, however, I never see anybody realize that the key to negative output impedance Midbass is to make sure that it is NOT the last channel. If after the Midbass goes a dedicated bass channel then all problems of negative Z might not manifest itself.
