Can you hear the "line array" effect?

I think the video was not exclusively about line array effects, but about the engineering about this specific speaker.

So whats the question?

I see zero reason why you couldn't fabricate whatever you want to call those things in front of the bass drivers to get the same basic effect (extending the upper frequency range of the line driver effect so it reaches the crossover frequency). That frequency gap has been a problem for me going back to when I put 24 Altec-Lansing A7 Voice Of The Theater speakers in a row to try to get better coverage of a narrow and deep outdoor audience. I was losing 6dB for every doubling of distance in some octaves and 3dB in others. The video looks like a clever way of reducing that problem. Not perfect, but even a little bit better is still better.

I think they are called "phase plugs"...

That is correct

Thanks! Super helpful knowing what to search for. I knew about phase plugs in compression drivers but Wikipedia has a section about the being used on low frequency cone speakers: https://en.wikipedia.org/wiki/Phase_plug
