My understanding of physics might be wrong, but that doesn't seem possible.
I would love to be disproved however.
What do Art and Ivan think?
I have ZERO experience with this-so the following based purely on "my thoughts".
1: I am very curious about the statement of lack of reflections and so forth. In their "simple drawings" they show a conventional speaker have a few "rays" of sound while theirs has lots. However a real speaker IS spewing rays out all over the place-not just a few 'arrows".
The whole idea to reduce reflections/reverb etc is to CONTAIN the sound and not have it spewing all over the place.
In the live video-it appears as if there is a good bit of reverb/reflections in the recording-about what I would expect in a room like the video was recorded.
I would really have to hear it to believe that.
2: I am with Art in that the "demo" of the mic not feedback was not that loud. And when you spread the output over a large area (not a single device) the SPL of each speaker is much less-and there is less of a chance for feedback-especially when you are right up against the speaker.
This is the reason a distributed ceiling speaker system is less likely to feed back-over a single or pair of speakers covering the same space at the same level. Each source is not that loud.
3: The one thing I never noticed was a mention of sound QUALITY. A single source of sound is simply going to be more accurate than multiples that are arriving at different times causing combfiltering. So with a whole "pile" of speakers, with a diffuse sound field-the sound quality is going to suffer-or so I would think. I just don't see how it could be as clear/natural.
There was a mention of 100dB spl at FOH in a room-but no weighting scale or time (slow/fast/peak etc). So that number could mean just about anything.
I am not saying it does not do what it says-just that I am very leary until proven otherwise.
I do agree that the thin profile is a good thing and would offer lots of options on speaker placement.
With only the one exception, the music that was playing was not being picked up by the camera mic-and is very possibly overdubbed-no way of knowing where the audio came from.
I would like to hear a recording from a mic on the camera out in the room-at a distance.
There are new cool things/approaches being done all the time-so who knows. Sometimes there are some serious "side effects" that are just "glossed over" and hoping the customer won't notice.
We will see how this works in the field. But it just seems to go against basic physics-that sound waves must obey
