Omnidirectional Speakers - Spreading Wave Motion

When I searched for omnidirectional speakers, various speakers were introduced.
However, strangely enough, when I looked at the details of each one, they all displayed prices as "pair pricing."

Omnidirectional, yet two speakers?
Where and how should they be installed, and where and how should they be listened to?
Omnidirectional sound should be naturally natural sound.
Natural sound certainly spreads evenly toward the universe.
It is wave motion itself.
If you hear a solo vocal coming from two speakers, can that really be called omnidirectional?
Even if it's not a human voice, take a violin, for example.
Sound spreads as wave motion from the contact point of string and bow toward space, toward the universe - so how exactly can two speakers express this?
It's puzzling.

The existence of two speakers means, logically speaking, that the listening position is limited to "here," doesn't it?
In the first place, when listening to sound or music, introducing logic makes it impossible to feel at ease, to relax, to feel calm.

I can almost hear voices saying "music is mathematics, it's made of logic," but while music may indeed be mathematical, what I want to discuss here is the environment for listening to music - please don't bring logic into the listening space and environment.
Even if told "stay still in this place and you'll hear natural sound," staying still itself is not natural.

True omnidirectional speakers spread wave motion.
Wave motion is waves that spread evenly toward space, toward the universe itself.

Humans originally lived within wave motion.
They lived only within wave motion.
150 years ago, speakers created directional sound. For hundreds of thousands of years before that, people lived within wave motion.
That's why natural sound causes no stress.
When you want to feel at ease, to relax, to feel calm, you cannot feel at ease, relax, or feel calm with stressful sound.

With omnidirectional speakers that have wave motion, you can feel at ease, relax, and feel calm.

Now, here they are - wave-motion speakers.
As proof, look, they've already been installed in places like these:
