yeah ok Dave, I know you rate bipole and omni as being the same
I'm not so certain about that
bipole will have two ver defined directivity
omni only has one
but interesting to look at it from the reflection side only
then omni and bipolar might be very similar
place the bipolar drivers in horisontal position, and then they suddenly are real omni polar
strange world
maybe you nailed it there
and the difference between this 'omni half space' and 'normal half space' would be directivity differences
might make the difference
nice looking, but looks like a dipole design, and not omni
now, if they were bipole, and turned 90 degr, maybe they could be called vertical omni directional
well, due to size I concluded that it could not be bipole, but maybe a bit too fast 'logic'
are front and back connected in phase, or out of phase ?
still, I think you need to listen 120-180 degr off axis on driver, to called omni
Wow , looks like you know the Artistic Audio speakers and its technology better than anybody else ???
Just because the speaker is unknown I wouldn't make any statements without listening to them and get more info about the technology behind it before I throw them into the waste bin of false arguments ?
Ok I'm out again , wrong thread .
I see no reason to be offended
noone commented on how they sound
I'm sure they sound great
but thats not what its about
I just commented on whether they really are omni speakers
and said I don't think its an omni polar
anyway, I still don't know if they are connected as bipole or dipole
I would still like to know ?

Dave, my reasoning for saying dipole is that with the drivers mounted almost face to face gives way too little air volume for the bipole configuration
well, according to a test it really is a bipole

yes ofcourse
point is, bipole needs a box with volume, just like any other drivers around
and two drivers need twice the volume as one driver
dipole does not need any box
the artistic audio speaker is bipole
and why I posted the picture and asked; where is the box volume
radugazon, sorry no info
it was presented by a member, some posts back
but you may find review etc, on google
The trouble with the measurement goes back to my whole idea.
If we can't figure out how to mic it to get a measurement, how would you mic a performance to get it to come out of the thing properly in the first place.
some claim that understanding of directivity and polar patterns is the key to any speaker design
well, maybe not all its about
but could well be what makes the omni polar different
it should not have any changes in polar patterns
in other words, 100% homogene
and then we do have reflections
but reflections are present with any kind of speaker
I dont see why you can't measure omni polar speakers

Any speaker's polar pattern can be measured.
Any omnidirectional speaker using more than a single point source will "look bad" in it's high frequency polar response.
An omnidirectional speaker will result in far more room reflections than a speaker that has directional control.
For people that prefer the addition of extra reflections, the added comb filtering and "spaciousness" of the added room reverberation, omni's will continue to be loved.
For those with even a passing interest in accurate reproduction of recorded music in typical listening environments, omni speakers will continue to be unpopular.
But since we no longer live in caves, there are many things that are in common to all listening rooms. Let's take the later Carlsson speakers (I am very happy with): a flat wall, perpencicular to floor and ceiling, floor and ceiling parallel and also flat, the speakers at the edge between floor and wall, the distance between floor and ceiling comparable to the distance between wall and listener.

With all this said, if someone were to give me one of the surviving pairs of JBL Aquarius 3 pre production prototypes, I wouldn't say no. They'd be ideal for background / ambient music while I'm working on the final draft of my doctorate (not the shortest process I've ever known).

what's the point of insulting each other?
would You say the same about people like authors of "Art of Sound Reproduction", "Total Recording" or about Linkwitz?
can't You see it's simply silly?
The idea is that in any of it's current iterations, it's terrible. I agree that if it was possible to do it properly, it would be great, much like how using 6 video projectors to turn every surface in your room would be great for movies, if there was source material to go along with it.
If you used 6 projectors to turn your room into a giant video of a fishtank I'm sure it would impress the neighbors, but would you watch a movie on it?
I'd love for there to be a way to get omnidirectional sound from source to speaker, but what we're talking about here is taking polar, or at the very best bi/dipolar recorded soundwaves and fire hose spraying it incoherently around in all directions.
