I am working on an exhibition where I want to use DIY, self-made directional speakers for transmitting interviews to the visitors.
Until now I have seen a couple of video on Youtube like the one listed bellow
This exhibition in Berlin seems to have used some type of directional speaker but I am yet unsure what exactly they have used. Link.
My question is as follows: What would be the best solution to include some directional speakers in my exhibition?
In case I build the diy model, from the video, will the voice from the interview be clear enough for the visitors to understand.
