Yes, I know what you mean but you didn’t compare to the most likely competition for superior bass.
these are superior to anything in weight I have heard and integration of bottom half to upper range making it the most coherent. I don’t consider corner horns anything more than room compromises and they are a solution if like Peter you have a 15x16 living room where you want to get the most of your living room combining it with audio. Competitions for those are vintage tannoys, AN-E, and in modern speakers audionec evo 2, I prefer the audionec more.
Altec 817 and Leif’s and a couple of other dual FLH I heard are all out speakers requiring space availability and to excel over anything else there is no competition except with other similar models
