Seeking directional speaker recommendations for a museum exhibit
I've been contracted to design sound for an exhibit at a children's museum about "being inside a thunderstorm and rainbow."
It’s a pretty small exhibit area with an open-floor plan, targeted to toddler age, and with a live foley component (thundertubes, rainsticks, etc). I am deeply concerned about sound bleed so I'm researching directional speakers. (Which will be supplemented by subwoofers and some practicals.)
I'm looking at Dakota Audio (FA-501), Brown Innovations (CT24-24 or Wide Dispersion Localizer Sound Dome), Focusonics (Model A) and Soundtube (FP6020-II).
What I’d like is for visitors (say, a small family) to be able to go to each area (maybe 7’x7’?), stand there and be immersed in the storm for a few minutes while looking at whatever it is they’re looking at, and then move on to the next area and listen to that storm phase, but without having to hear too much of the other areas. In other words, sort of a curtain of sound blended around the room but specific details as you move around each "area" and explore the storm.
I have no idea what the museum’s budget is. They told me to do the research and they’ll let me know!
Thoughts on the above brands? Or others? Or best practices? I have never done this before and neither has the museum.
