@David A One comment about your Kittyhawk story: while it's undoubtedly entertaining, it's not directly germane to the current discussion. Flight is an objective (measurable, repeatable) phenomenon, which is not what we have here.

To be analogous to Kittyhawk, we first have to make an objective observation - for example, that there's a systematic change in frequency response between the two speaker connection methods - and then investigate how current science or engineering explain it (or not).
