Is it omni?
no, I don't think its omnipolar
more like multi bipole
think of what we do know happens with side by side mounted drivers
What was the question again?
Oh yeah... I don't know the answer.
I have spent some time listening to dipoles (Quads) and omnis. The first omnis I heard were part of a cheap integrated "stereo system" my father bought back in the '70's. Zenith? Squat little boxes with upward-firing drivers with a sort of "disperser" (I guess they would call it a "lens" now) to spread the sound out. Driven from an integrated amp/turntable unit. Not pretty. They sounded better than they had any right to.
Last year I built a pair of Linkwitz Plutos. They kick ***. I continue to have "Pluto moments" where I am startled by them. It's true they are not really omnis, but they are omni where it matters, and they do a lot of other things right.

This past weekend I listened to an updated version of the Linaeum tweeters on a High Emotion Audio Pyra Bell 7 Pyra Bella 7 - Products - High Emotion Audio with a Peavey 18 inch Black Widow bass units crossed over at 80Hz and bi-amplified. A very nice speaker and I can only hope that some day the tweeter will be available to DIY......

yes, very, I mean very well said!
AudioPro has a model following Carlsson design principles:

typical flooder, short, everything up-firing
I am a tad confused by this
Reading this article (and going off the pictures) I am lead to believe that normal speakers only fire forwards and dont ever reflect off nearby walls or the back wall, or the floor, and will never fill the room with moving particles of air
(this is actually true, my speaker is to my right and no matter how loud I put it I can only hear it when I'm stood infront of it) </sarcasm>
But if you fire them upwards they suddenly start producing sound in all directions, which then reflect off everything.
My point is this sounds like utter marketing rubbish to me. The speaker is firing at the ceiling (and will reflect off it) just as a normal floor stander fires at the back wall (and then reflects off it)
Yes they are tilted slightly, but then so are normal speakers, they rarely fire directly at the back wall and will be tilted inwards slightly (except for mine, I do have mine parallel to the walls)
not really, or at least - it depends, anyway, it certainly doesn't apply to a flooder, by it's nature
have You read this?

That thing reminds me of a Bose 301. Maybe the 301 would have made a better speaker than coffee table had they spent more than 87 cents on the tweeters.
I've always thought that Omni was an interesting idea, but to go along with it, wouldn't you need recording equipment designed to capture it properly?

I've no idea what 'this' is supposed to be, other than a link to the thread we are currently on. By definition, an omnidirectional speaker will increase the ratio of reflected to direct radiation (unless you happen to listen to loudspeakers in an anechoic chamber, or in the middle of a field).

invalid link? in that case let me quote:
so
yes, it will, surely - but we don't know the effect of this from psychoacoustical point of view, the after therefore part of Your statement is not necessarily correct:
short & simple it is, cannot deny
Sigh. As I have stated, an omnidirectional speaker in a room significantly increases the ratio of reflected to direct radiation. By definition, this means the end results are more heavily dependant upon the acoustic environment, and its absorbitions, reflections etc. than a conventional loudspeaker. If you are unable to grasp this basic point, there is no possibility of logical discourse on the matter.

Well, not quite. Not omnidirectional in the vertical, only in the horizontal, like most.

The perfect speaker is a small point source dispersing sound equally into all directions.
OMNI designs are not very popular because many of them don't meet those requirements very well. Many small bookshelf type speakers with a 4" woofer and a 1" tweeter come close to being omni sources and are also very popular.

yes indeed, if one is unable to grasp the basic point, there is no possibility of logical discourse
but back to the topic- again I think Your statements are not necessarily correct -> what kind of acoustic environment have You got in Your mind?
truth is that in a typical listening acoustic environment that is a typical living room omni - especially a flooder type - is much less dependant than a conventional loudspeaker and actually that is quite easy to explain why, and the key is exactly the increase of the ratio of reflected to direct sound, paradoxical? I say - think about it and then sigh
Only if it is used in conjunction with the perfect microphone that captures sound equally in all directions.
Say we could make a microphone like that, where each microscopic point on a sphere shaped device captured a perfect point-source of what arrived at it. What would the wiring look like on such a beast? There would literally be half a million or more wires coming out of it, each one labelled and identifiable, so that it could go into it's equally mythical recording device.
A tape? It would be dozens of meters wide. A digital unit? Terabytes per second.
Until we have figured out a way to to capture it properly, all we're doing is sending the same signal that we've captured with a few strategically placed microphones and then trying to play it back through a speaker that just sprays sound out in directions that we never actually recorded a proper input from and then expecting it to be a truthful reproduction with accurate time and space.
It might be a neat effect, spraying sound waves around our rooms with oddly placed drivers and bouncing them off of every surface. I bet it's impressive, but we can't really convince ourselves that it's an accurate reproduction of what was really going on at the recording venue, can we?
