Hey there everyone! Hope you're all well.

I wanted to ask if anyone on the group has experience setting up a
multichannel rig for a dome setup? Specifically designed to play Ambisonics.

I've been working with a team looking to build a VR hemispherical dome that
can display 360 video alongside Ambisonic content. The design for the dome
structure is complete and now we're just figuring out the sound component.
The sound is meant to fit seamlessly, and no obstruction should be on the
floor.

The dome is roughly 7m diameter, and built out of a fibre glass type
material. We're planning to have a two layer type sound setup, so with
roughly 14 speakers per layer plus a voice of god and a sub so (14-14-1.1).
I was thinking that it could be an interesting idea to mount the sub in the
ceiling above the VOG position, my reasoning being that the sub should
emanate evenly across the floor of the dome, and it would prevent the need
to have multiple subs outside the dome structure on the floor.

I've never setup in a dome before and I can imagine the acoustics must be a
little strange. Upon watching this video (
https://www.youtube.com/watch?v=JpdRYv9xA9w), I seem to get the feeling the
task may get quite interesting. I'm hoping someone may have some experience
with this.

Some problems that I think may occur:
1. A boomy bass at floor level.
2. Room resonances and standing waves that don't seem to be very well
studied.

I think first port of call for the Ambisonic setup is to ensure that each
speaker is calibrated to be the same loudness and time delay at the
listening position. From there, I've been looking into applying an averaged
DRC filter over the entire listening space to each loudspeaker to try get
the most accurate speaker response for the listening area although I know
this is quite a tricky challenge. I'm hoping that the DRC may help to
mitigate some of the room resonances, however, I'd love to get a second (or
more) opinion on how this would affect the setup.

Anyone with any advice or resources on this would be very much appreciated!

Thanks in advance.
