several reasons I believe
first, most of pros and also audiophiles prefer unnatural sound of front firing speakers, and there is a marketing trend set against omni as something radically different from the front firing mainsteram
second, prevailing acoustical theories cannot explain behaviour of an omni in a room, and lack of theory results in imperfect omni speakers because manufacturers don't know what they are doing really
third, omnis need different room interface than front firing speakers and rarely they are set up proprely
forth, people are mentally uhm uhm er... conservative and reluctant to try things different
fifth, there are some omni speakers that are quite popular, at least in the audiophile DIY community - Plutos for example, in spite of the fact that Linkwitz doesn't know either how this omni works and why ;-)

I guess with B&O in-car systems gaining popularity and tv exposure it might encourage more home audio companies to start looking at producing omnis.

omnipole = omni directional. I usually bunch bipoles in with them.

Stu Hegemann was an early proponent of omni in NA (see Morrison Audio fine audio speakers and electronics.), there were quite a few in the UK (some of the Lowther corner horns come to mind). Electrohome in the 60s & 70s really pushed the concept into homes... they had a zillion different omnis similar to the Mirage (i expect Mirages patent only covers the specific reflector shape they use -- anyone got a patent #?)

So would a bipole qualify for this discussion? I've considered bipole for the benefit of floor bounce correction and baffle step compensation.

you are completely at the mercy of the room's acoustic. controlled dispersion usually results in Higher Fi

OTOH, if you're going to spend a gazillion dollars on a first-rate omni like the MBLs mentioned above, it's not a reach to spend 1.05 gazillion dollars on the omnis plus room treatments.

I am quite happy with line arrays in walls, I hear stereo (and surround) everywhere in my house, even when I sit now in the office and daughter watches movie in living room, I hear multi-dimensional sound, as if "it is there".

It is like an omni field, but created by more than one speaker.
Nothing in the universe is perfect. The ideal things are the ones that are most optimal. Optimization criteria, what matters. When I hear "No Compromise Design", I want to take a sledgehammer and test how impact-proof it is.

IMHO, real full range omnis are not popular because they need either specific drivers (MBL, German Physics...), or some stuff around ( Duevel) or a lot of drivers (Raal's Eternity : think of the bill for a DIY cloning).
This with the R&D (and the high end positioning) results in a relatively expensive set of speakers. On the DIY side, is the more popular pluto a full range omni ? Hum, not that much. A flooder with frontal tweeter.
An other caveat for the omnis, is that they sound better in wide rooms where the reflections will be delayed enough.

Anyway, some people like. I have seen a photo book in a Singapore shop with as much customers than a teenager has friends on facebook. 35.000 US$ the speakers pair...

When you refer to "omni" what frequencies are discussed?

All typical box speakers are omni at lower frequency. I had built a linkwitz pluto clone and they are omni to 3.5 khz. This is uniform enough and they sounded great. As dipoles they really need space, and I guess one of the factors why they're not pupolar? Most people/wife wants speakers out of the way.
