Why are OMNI speakers not more popular?

In practice (in terms of clarity) Pluto is at least equally revealing (and mostly far better)compared to any other speakers I have owned or listened to, reflections or no they are highly revealing of production quality compared to countless high quality home hi-fi speakers in all shapes and sizes (box or otherwise), Studio monitors and ESL's.

absolutely, in case of speakers properly designed and properly set up there is no alleged trade off between clarity and spaciousness
 
in fact such a true idealised omni is definitely NOT what we need for high fidelity sound reproduction at home as it would make much harder to get rid of detrimental effects of of floor and ceiling reflections

Isn't the point of a true omni to get all those reflections too?

If I understood correctly the idea behind Carlssons omnis is to stop seeing an anechoic chamber as the ideal room but instead let the room be heard through the reflections which in the end creates a nice and natural sound.

who knows

I see the Carlsons as an attempt to make an easy 'in wall' design
with compromises, ofcourse
it was a commercial speaker, which no doubt made it even harder

it tested quite well, but unfortunately didn't look so good
and certainly not 'political correct', in the world of hifi

but mr Carlson himself was certainly not ordinary
he may have been one of the first to raise all his cables from the floor, with small blocks of wood
funny that he should design such a 'daft' speaker

as said before, I think he used poor drivers
and crossover technology wasn't at its the best, at that time
very far from the understanding and knowledge we have about it today
and it ain't one bit easier, still
like they say, the more we know, the harder it gets

yes, therefore pursuing the goal of 360 degrees omni is pretty pointless, pun intended ;-)

If I understood correctly the idea behind Carlssons omnis is to stop seeing an anechoic chamber as the ideal room but instead let the room be heard through the reflections which in the end creates a nice and natural sound.

IMHO the idea is that as it is hopeless and also pointless to try to convert a room into an anechoic chamber it is necessary to handle the reflections differently

also Carlssons were much more than just
an attempt to make an easy 'in wall' design
with compromises

the 'in wall' element was clearly there but very important part (at least of most developed Carlssons designs) was also specific handling of floor and ceiling reflections - making the speakers very short and slanted and the use of felt around speakers aimed at reducing the floor reflection and at making the ceiling reflection more delayed and at the same time more resembling the direct sound

it tested quite well, but unfortunately didn't look so good
and certainly not 'political correct', in the world of hifi

nonetheless they were probably the most successful speakers of their time in Sweden
Carlsson should have teamed up with IKEA, then the world would become entirely Carlssonian by now 😀

I didn't know that! 😀

If perfect omni isn't needed, then what about bi-pole?

In a bi-pole speaker, if the drivers' sizes and xover are well considered, then each side of the the speaker can be very wide. And such bipole can be very close to omni in a room.

Any input?
 
such bipole can be very close to omni in a room.

then it is also to be avoided for the same reasons, isn't it?

it seems to me that for realistic sound reproduction we need to:

1) acoustically mask the speakers as real distinct sound sources
2) acoustically mask the room as the real sound space

to achieve this first of all we need to:
1) get rid of the floor reflection which in the first place unmasks the speakers as real distinct sound sources
2) make laterally reflected sound as similar to the direct sound as is needed for precedence effect to work because otherwise we start to hear the room that is the wall reflections as real distinct sound sources that mix up with the speakers as real distinct sound sources to create a mixed-up soundfield
 
When people read "bipole", they visualize something with one driver shooting to the listener, one driver shooting to the back wall (about this, for those that haven't seen it, there is something interesting in this good thread).

But some people put the bipole axis perpendicular to the listening axis (we satisfy then the first condition of Mr Graaf). In some configurations, it's also possible to transform the bipole in quadripole, a very close approximation of an omni source. Then the fourth condition is satisfied...already 2/4

another way of satisfying those requirements is Beveridge Line Source ESL with Beveridge Lens and in Beveridge speaker placement where the vertical reflections are completely absent because of infinitely long line sound source, the speakers are integrated into the side walls hence side walls reflections are not there anymore, as to the front/back/opposite wall reflections they are much more delayed than typical and practically identical in their content to the direct sound thanks to uniform 180 degrees sound coverage if Beveridge Lens

back-to-back Stereolith-like-set-up is another one
 
maybe something like this

I'm inspired by the RAAL Open Baffel omni woofer section
An externally hosted image should be here but it was not working when we last tested it.


I'm in the designing mode at the moment, at will make som tests to hear what different OB subs sounds like in my room. The OB subs will not be dipole. I have four 10" woofer per side and one mark audio CHR-70. I will try the markaudio drivers, both with and without reflector and on a front baffel like tinitus shows. A fullranger might not be ideally in omni speakers, but I will give it a try.
