Levels- and spectra-pathing symmetrical arrays of monopoles

This is about spectra-pathing ("multi-way") loud-speakers 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 loud-speakers, not stadium ones. While spectra-pathing enables large power at wide band-width, 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.

The natural solution is a symmetrical arrangement of lo-pass monopoles embracing a hi-pass one, combined with a cross-over of first order.

When Germans started to loose ground in World War II, wide-range drivers playing from Large E to 10 KHz were state of the art. Mister Eckmiller developed a co-axial two-spectra-paths driver consisting of hi-pass encircled by lo-pass piston. But for mass...
