The engineering question is: how can we best use the rear wave? And this answer is, pass 'em around to dump next to the speaker output with a delay that puts their phase in the most helpful point.
Not a bad idea and can be effective for some loud, PA, and other low quality sound installations. But a system that traffics in phase arithmetic, you get boost and you get cuts.
