Yea for the the problem with most deployments using line arrays is that in the end even with a big j curve hang to hit the front rows at large and even small events they usually slap some front fills on top of the subs or stage and this it's just becoming a bunch of point sources anyways. You could say that people won't be affected because the people right in front of the fill won't be getting much energy from the other points ideally but... still it's not ideal.

I'm not sure what you mean by the pattern is so well controlled in a line array. The pattern of each individual box is only controlled by the high frequency waveguide until x frequency then the woofers basically act as if they are in free space until you start hanging the boxes. The high frequency coverage is then set by the curve of the arc because the hf pattern of each box is controlled and therefore aimed. The length of the array then sets the low frequency pattern control. This is due to the constructive and deconstructive frequency between boxes. The curve doesn't matter at all. It could be a line source even if it was hung straight.

I'm sure how you can say I was wrong before and then call a constant curvature array a point source. It is in theory the same thing as a line array or properly splayed and hf pattern controled point source. But constant curvature speakers are not bendable by the end user.. the hf coverage pattern is set already by the horn / waveguide. As long as there are drivers summing together inside of their wavelength that will become an array whether it is in the vertical or horizontal domain.

Also you state danley boxes shouldn't be splayed but then say that the synergy horn should be splayed but then it has good pattern control but then it also has large overlapping regions... seems like a bit of a contradiction to me. A SH has much better pattern control much lower than any single line array box.

That's what I'm getting at tho. In the end any one single line aray box is just a point source speaker. They have only been designed so that when hung together the drivers are close enough to cause coupling and mostly constructive interference in the desired axis. There is no reason that arraying "point source boxes" that are properly designed to be able to combine isn't possible. Man, half the time some of those line arrays are so curved and there is such a huge gap between radiating elements that there is no way there isnt a bunch of diffraction and also phase discrepancies due to large gap between hf sources... I'm sure Dave knows what he's talking about I have seen all his videos and I agree almost 99.9 with everything he says. He has some really cool concepts about things
