This is about spectra-pathing ("multi-way") loudspeakers made of several monopoles, in explanation omni-directional sound sources, but I really mean direct radiators as opposed to horns, which are more uni-directional. I think about home, rehersal and club loudspeakers, not stadium ones. While spectra-pathing enables large power at wide bandwidth, seams between paths are usually audible, altho that could have been avoided rite from the start, at least technically. But instead of fixing problems at source, one has relentlessly used power to paint over them.

Computers can cover up phase distortion, which has been introduced by common spectra-pathing, and improve beamwidth. But the natural solution is a symmetrical arrangement of lopass drivers embracing one hipass driver, an arrangement commonly referred to as D'Appolito arrangement, combined with a cross-over of first order.

When Germans started to loose ground in World War II, widerange drivers...
