The (John) Koval Mod of the Original Quad turned this 3-way loudspeaker into a 2-way. John told me he did it to counteract the falling high-frequency response of the speaker, the mod adding the output of the narrow super-tweeter to the wider tweeter panel. I didn't know enough at the time (mid-90's) to ask him if that didn't cause a problem with its off-axis response (due to the increased beaming of the now-wider tweeter).
