Giving credit where credit's due, that's Earl Geddes' concept. I don't think he's the first to criss-cross speaker axes in front of the listening position, but he is (to the best of my knowledge) the first to specify the combination of 90 degree constant-directivity waveguides, pattern-matching in the crossover region, AND 45 degrees of toe-in, or whatever amount of toe-in is practical such that the speaker axes criss-cross in front of the listening area. So the smart thing that ye olde designer here did was to pay attention to Earl!
