And the phase interaction becomes greater.

It depends on the wavelength. One of the "points" of a line source is that you
have phase interaction among the drivers.

And it depends on the size of the drivers and correspondingly the spacing.
Arrays with more, cheaper, smaller drivers can drive the point where the
comb filtering gets bad up to higher and higher frequencies.


But that will also reduce the footprint of the comb filtering ( in the
plane of radial distance around the axis of the column ).

Which is why the Bose L1 works better than the Shure Vocalmaster. But really,
they have a lot in common (including the intended use).


I knew a guy who built cabinets to replace Vocal Master columns with
2X15 and a horn. They sounded pretty good. He sold quite a few of
them.

So it's not like the cabs were exactly prized.
